He needs to rule out other causes, which makes sense.
I know that my blood is filled with, I can't remember exactly, but it's inflamation. Every time I have blood work done, the dr would come in and ask if I had any pain. HELLO - I have Fibro is what I would scream in my head. New dr. who doesn't give me enough attention to my pain. She gives me meds, but doesn't really have any answers either.
The Rheumatologist that diagnosed me told me to wear a cervical collar for sleep, and suggested heating pad, exercise, meds, etc. but seemed to understand the pain.
When I can, I walk in water, not on it, and it helps because I'm not so uncomfortable after.
Ask him if there is someone he can recommend you see, when you go back for the results.
Good luck.
