What type of doctor should i see..?

I would see a chiropractor first. Chiropractors look for the root cause of your pain and headaches, whereas MD's will just prescribe anti-inflammatories or stronger pain meds to cover up the pain but not treat the actual problem. Sometimes from playing contact sports or car accidents or other traumas the bones in your spine can become misaligned and irritate your nerves causing pain, muscle spasms and other problems. Chiropractors re-align the bones to relieve irritation on the nerves and this corrects the problem. If you see a chiropractor and when they examine you they feel that you have severe neurological damage that requires a referral they will send you to a neurologist or whatever referral is appropriate. I would recommend this route because chiropractic care is non-invasive but extremely effective and it is always better to try something non-invasive first before resorting to drugs or surgery, both of which can be risky.
