Which is the best doctor to see for musle pain that comes and goes for a few months ?

Your doctor: Would suggest seeing your primary care doctor. You need a good exam and review of your symptoms. Based on the possible causes for your symptoms a specialist referral will be made if needed.

Muscle Aches: Hi. I would start off with your primary care physician - family medicine or general internist. They should be able to look over your medications, histories, physical and try to pinpoint the cause. If needed they can initiate lab work and other testing. Depending on the initial work up - they may refer you to a sub-specialist for further evaluation or treatment.
