Exercises for Knee Pain Relief
Exercises for Knee Pain Relief Scott 47 Views • 2 years ago

Hey everyone! When I started posting more squat and lower-body workouts last week, I got many requests for this video. I actually had already had a knee pain video, but I felt like I could make it a lot better, so I remade it.

For more information, check out my friend ‎@ChrisRaynorMD aka @stablekneez on Instagram. Dr. Chris is a great surgeon, creative content creator, and all around good guy. He knows a LOT more than I do about this stuff. If you're interested, check him out!

Knee pain can be caused by MANY things, and this video is not intended to diagnose or treat any medical conditions. Some issues cannot be solved with exercise or physical therapy alone.

However, I've found that building up do doing squats with a full range of motion can help with knee pain. It's interesting, because there are some fitness figures that are adamantly against deep squatting because they claim it is BAD for the knees. I like it, and I've found it to be a very natural position. However, I do think that many people may not be prepared for it. Like any exercise, it can potentially hurt you if you're not acclimated to it. You can use your arm to assist you through the motion until you're able to do it without your arms with no pain. I have a full YouTube video on this: www.hybridcalisthenics.com/deepsquat.

Beyond this, sometimes strengthening our calves and hamstrings can "mysteriously" fix our knee pain. Both of these muscle groups support the knees.

On the other hand, sometimes these muscles are simply too TIGHT. You muscle fibers may be getting too tight and constantly trying to hyperextend your knees. Savor some calf and hamstring stretches.

I should point out that my chosen hamstring stretch in this video, standing toe touches, are controversial to some. Again, I like them, so they're shown here. If you are against them or they hurt you, you're very welcome to choose a different hamstring stretch.

Finally, I talk about isometric exercises like the horse stance and wall sit that seem to help with knee pain.

I touch upon synovial fluid, which is largely responsible for healing and nourishing our joints. Synovial fluid mostly circulates with movement, so I've included some knee "circles."

Hope this helps!

The basics of the ECG
The basics of the ECG samer kareem 17,217 Views • 2 years ago

This short course reviews the main features of EKG tracings. A method for analyzing EKGs is also presented. This method includes assessment of rhythm, calculating heart rate, observing P-wave forms, measurement of EKG intervals and segments and the evaluation of other relevant waves.

Medical Emergencies Caught On Live TV
Medical Emergencies Caught On Live TV Scott 69 Views • 2 years ago

Live TV is so exciting because anything can happen, and sometimes that means injuries. Today I'm reacting to injuries and medical emergencies that happened on live tv. We're talking America's Got Talent, American Idol, newscasters having strokes, dehydration, Wendy Williams overheating, swallowing swords, being hit with a motorcycle, vasovagal syncope, drowning, Dan Harris, and magical tricks like David Blaine's needle in going wrong. Which clips did I miss? Let me know down below.

I LOVE reading your comments and take your suggestions seriously. If there’s a subject you want me to discuss or something you’d like for me to react to, leave a comment down below. Many of my videos have been born out of suggestions directly from you, so don’t hold back!

Simple Running Skin Closure
Simple Running Skin Closure samer kareem 12,390 Views • 2 years ago

A simple continuous stitch can be a useful technique for skin closure when speed is important, e.g. closing a scalp laceration on a screaming child. The simple running, or continuous suture, is begun in the same way as a simple interrupted suture.

Nerve Anatomy
Nerve Anatomy samer kareem 12,848 Views • 2 years ago

Nerves are the organs that make up the peripheral nervous system (PNS). They serve as information pipelines that allow the brain and spinal cord to communicate with other tissues and organs. Inside the nerves are the axon processes of sensory and motor neurons (nerve cells).

Chalazion Removal
Chalazion Removal samer kareem 19,061 Views • 2 years ago

Chalazions are extremely common, and having a sound surgical technique to drain a chalazion is a fundamental in general ophthalmology and oculoplastic surgery. I believe one of the biggest downfalls in treating chalazions is inadequate local anesthetic. Please that both the outer and inner surface to the eyelid need to receive local anesthesia to make the patient totally comfortable. It is important to be careful in delivering the local anesthetic and making sure you have control of the head position, and the position of your needle is bent to minimize any possibility of contact with the globe.

Tonsillitis
Tonsillitis samer kareem 2,393 Views • 2 years ago

Tonsillitis is inflammation of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. Signs and symptoms of tonsillitis include swollen tonsils, sore throat, difficulty swallowing and tender lymph nodes on the sides of the neck. Most cases of tonsillitis are caused by infection with a common virus, but bacterial infections also may cause tonsillitis. Because appropriate treatment for tonsillitis depends on the cause, it's important to get a prompt and accurate diagnosis. Surgery to remove tonsils, once a common procedure to treat tonsillitis, is usually performed only when bacterial tonsillitis occurs frequently, doesn't respond to other treatments or causes serious complications.

Spleen
Spleen samer kareem 5,337 Views • 2 years ago

The spleen, a spongy, soft organ about as big as a person’s fist, is located in the upper left part of the abdomen, just under the rib cage. The splenic artery brings blood to the spleen from the heart. Blood leaves the spleen through the splenic vein, which drains into a larger vein (the portal vein) that carries the blood to the liver. The spleen has a covering of fibrous tissue (the splenic capsule) that supports its blood vessels and lymphatic vessels. The spleen is made up of two basic types of tissue, each with different functions: White pulp Red pulp The white pulp is part of the infection-fighting (immune) system. It produces white blood cells called lymphocytes, which in turn produce antibodies (specialized proteins that protect against invasion by foreign substances). The red pulp filters the blood, removing unwanted material. The red pulp contains other white blood cells called phagocytes that ingest microorganisms, such as bacteria, fungi, and viruses. It also monitors red blood cells, destroying those that are abnormal or too old or damaged to function properly. In addition, the red pulp serves as a reservoir for different elements of the blood, especially white blood cells and platelets (cell-like particles involved in clotting). However, releasing these elements is a minor function of the red pulp.

Left side abdominal pain

Dehydration can also be a cause of kidney stones. A common symptom is having a lower left abdominal pain, fever, nausea, groin pain and vomiting. Lower left abdominal pain can also be caused by an infection of the kidneys. It usually begins with the bladder and then reaches out to the kidneys.

Liddle's Syndrome
Liddle's Syndrome samer kareem 1,850 Views • 2 years ago

Liddle syndrome is an inherited form of high blood pressure (hypertension). This condition is characterized by severe hypertension that begins unusually early in life, often in childhood, although some affected individuals are not diagnosed until adulthood. Some people with Liddle syndrome have no additional signs or symptoms, especially in childhood. Over time, however, untreated hypertension can lead to heart disease or stroke, which may be fatal.

Anaphylactic shock
Anaphylactic shock samer kareem 1,572 Views • 2 years ago

Anaphylaxis is a severe, potentially life-threatening allergic reaction. It can occur within seconds or minutes of exposure to something you're allergic to, such as a peanut or the venom from a bee sting. The flood of chemicals released by your immune system during anaphylaxis can cause you to go into shock; your blood pressure drops suddenly and your airways narrow, blocking normal breathing. Signs and symptoms of anaphylaxis include a rapid, weak pulse, a skin rash, and nausea and vomiting. Common triggers of anaphylaxis include certain foods, some medications, insect venom and latex. Anaphylaxis requires an immediate trip to the emergency department and an injection of epinephrine. If anaphylaxis isn't treated right away, it can lead to unconsciousness or even death.

Vertigo
Vertigo samer kareem 7,080 Views • 2 years ago

There are a number of different causes of vertigo. Vertigo can be defined based upon whether the cause is peripheral or central. Central causes of vertigo arise in the brain or spinal cord while peripheral vertigo is due to a problem within the inner ear. The inner ear can become inflamed because of illness, or small crystals or stones found normally within the inner ear can become displaced and cause irritation to the small hair cells within the semicircular canals, leading to vertigo. This is known as benign paroxysmal positional vertigo (BPPV).

Rectocele
Rectocele samer kareem 16,875 Views • 2 years ago

-Rectocele is a relatively common condition in older women and is characterized by the displacement of the rectum through posterior vaginal wall defect(s). The condition is typically caused by damage to the rectovaginal septum incurred during vaginal childbirth and is exacerbated by periodic increases in intraabdominal pressure (e.g., when laughing or coughing) and the effects of gravity. Women with symptomatic rectoceles who are poor surgical candidates may be treated with pessaries, which are structures designed to support the vaginal wall. Pessaries should only be used in conjunction with vaginal

Endometrial Cancer
Endometrial Cancer samer kareem 7,942 Views • 2 years ago

Endometrial cancer is a type of cancer that begins in the uterus. The uterus is the hollow, pear-shaped pelvic organ in women where fetal development occurs. Endometrial cancer begins in the layer of cells that form the lining (endometrium) of the uterus. Endometrial cancer is sometimes called uterine cancer. Other types of cancer can form in the uterus, including uterine sarcoma, but they are much less common than endometrial cancer. Endometrial cancer is often detected at an early stage because it frequently produces abnormal vaginal bleeding, which prompts women to see their doctors. If endometrial cancer is discovered early, removing the uterus surgically often cures endometrial cancer.

Ectopic Pregnancy Surgery
Ectopic Pregnancy Surgery samer kareem 4,814 Views • 2 years ago

An ectopic pregnancy results when a fertilized egg implants outside the uterus. Unfortunately, there's no way to transplant an ectopic pregnancy into your uterus, so ending the pregnancy is the only option. About 2 percent of pregnancies are ectopic. Because ectopic pregnancy is potentially dangerous for you, it's important to recognize the early signs and get treatment as soon as possible.

Modified Radical Mastectomy
Modified Radical Mastectomy samer kareem 4,357 Views • 2 years ago

A modified radical mastectomy is a procedure in which the entire breast is removed, including the skin, areola, nipple, and most axillary lymph nodes; the pectoralis major muscle is spared. Historically, a modified radical mastectomy was the primary method of treatment of breast cancer. [1, 2] As the treatment of breast cancer evolved, breast conservation has become more widely used. [3, 4] However, mastectomy still remains a viable option for women with breast cancer. [5, 6]
