Your headache symptoms can help your doctor determine its cause and the appropriate treatment. Most headaches aren't the result of a serious illness, but some may result from a life-threatening condition requiring emergency care. Headaches are generally classified by cause: Primary headaches A primary headache is caused by overactivity of or problems with pain-sensitive structures in your head. A primary headache isn't a symptom of an underlying disease. Chemical activity in your brain, the nerves or blood vessels surrounding your skull, or the muscles of your head and neck (or some combination of these factors) can play a role in primary headaches. Some people may also carry genes that make them more likely to develop such headaches. The most common primary headaches are: Cluster headache Migraine (with and without aura) Tension headache (also known as tension-type headache) Trigeminal autonomic cephalalgia (TAC), such as cluster headache and paroxysmal hemicrania A few headache patterns also are generally considered types of primary headache, but are less common. These headaches have distinct features, such as an unusual duration or pain associated with a certain activity. Although generally considered primary, each could be a symptom of an underlying disease. They include: Chronic daily headaches (for example, chronic migraine, chronic tension-type headache, or hemicranias continua) Cough headaches Exercise headaches Sex headaches Some primary headaches can be triggered by lifestyle factors, including: Alcohol, particularly red wine Certain foods, such as processed meats that contain nitrates Changes in sleep or lack of sleep Poor posture Skipped meals Stress Secondary headaches A secondary headache is a symptom of a disease that can activate the pain-sensitive nerves of the head. Any number of conditions — varying greatly in severity — may cause secondary headaches. Possible causes of secondary headaches include: Acute sinusitis Arterial tears (carotid or vertebral dissections) Blood clot (venous thrombosis) within the brain — separate from stroke Brain aneurysm (a bulge in an artery in your brain) Brain AVM (brain arteriovenous malformation) — an abnormal formation of brain blood vessels Brain tumor Carbon monoxide poisoning Chiari malformation (structural problem at the base of your skull) Concussion Dehydration Dental problems Ear infection (middle ear) Encephalitis (brain inflammation) Giant cell arteritis (inflammation of the lining of the arteries) Glaucoma (acute angle closure glaucoma) Hangovers

Some of these advancements include the use of robots to perform the surgery and the use of computer mapping scanners and software and even 3D printers to make the artificial knee implant. We are also seeing a lot of different advances being made by the medical device manufacturers.Some of these changes are designed to make the devices more durable than the 10 to 20 years they are currently rated to last. This is important when younger patients who are years away from being considered elderly have a total knee replacement, they will typically need another artificial knee implanted at a later date since they are likely to outlive the implant, which doesn’t always happen with elderly patients.

After 11 years of my work on my new migraine surgery, I start to do migraine surgery in all 4 principal places - places # 1 (STA) both sides, and places # 3 - Occipital artery also from both sides.

This is a minimally invasive surgical technique using an endoscope to remove any type of lumbar disc herniation - prolapsed, sequestrated or migrating discs. This technique does not employ any specialist instruments.The procedure involves two 5 mm portals employed beside the midline at the appropriate level of disc prolapse and the approach is interlaminar. The success rate of this technique in my hands is more than 90%
