Hello~I think that your best bet would be to see a chiropractor, you sound like you have pinched nerves, they will definitely cause the issues you are having. The chiropractor will take some x-rays, read over them and discuss a plan of action. After a few treatments you should start to feel better.
Another possibility could be a TMJ issue.
The temporomandibular (tem-puh-roe-mun-DIB-u-lur) joint (TMJ) acts like a sliding hinge, connecting your jawbone to your skull. You have one joint on each side of your jaw. TMJ disorders — a type of temporomandibular disorder or TMD — can cause pain in your jaw joint and in the muscles that control jaw movement.
The exact cause of a person's TMJ disorder is often difficult to determine. Your pain may be due to a combination of factors, such as genetics, arthritis or jaw injury. Some people who have jaw pain also tend to clench or grind their teeth, although many people habitually clench or grind their teeth and never develop TMJ disorders.
In most cases, the pain and discomfort associated with TMJ disorders is temporary and can be relieved with self-managed care or nonsurgical treatments. Surgery is typically a last resort after conservative measures have failed, but some people with TMJ disorders may benefit from surgical treatments.
Symptoms
Signs and symptoms of TMJ disorders may include:
•Pain or tenderness of your jaw
•Pain in one or both of the temporomandibular joints
•Aching pain in and around your ear
•Difficulty chewing or pain while chewing
•Aching facial pain
•Locking of the joint, making it difficult to open or close your mouth
TMJ disorders can also cause a clicking sound or grating sensation when you open your mouth or chew. But if there's no pain or limitation of movement associated with your jaw clicking, you probably don't need treatment for a TMJ disorder.
When to see a doctor
Again, seek medical attention if you have persistent pain or tenderness in your jaw, or if you can't open or close your jaw completely. Your doctor, your dentist or a TMJ specialist can discuss possible causes and treatments of your problem. Sometimes chiropractors can help this as well.
Hi
Pinched nerves can be like that. They change with posture as your muscles work differently and last as long as there is a problem, unless you do something about it. I have a bad one in my neck/shoulder area (I didn't even feel the pain there at the time) which caused pains on the back of my head on the left and have been going to physiotherapy for 3 months to help it and am only feeling better now.
Recovery is slow as muscles tend to tighten involuntarily over time and other muscles are underworked in all the wrong places and it takes time for the adjustment to be fully effective.
If you are worried you should pursue it with a doctor to eliminate anything else, but at the same time a visit to a good physio/chiropractor can be of tremendous help.
Hope you feel better soon.
