You need a Rheumatologist.
And don’t let anyone make you feel like your symptoms are not real, and all in your “head”.
If a doctor or nurse implies that and dismisses you, leave and find a new doc.

Fibromyalgia is an over reaction to pain by the brain. It is real.

If you are on Medicare, go on their site where you can find a doctor.

Wishing you the best.
