Yes i have it in both elbows and up my forearms, it is a sympton of the fibromyalgia.

I would suggest going to a physical therapist and asking if they can do Dry Needling.

You might try trigger point injections and/or cortizone shots? My fibromyalgia specialist does this on my arms and shoulders.

Yes I ha e this deep pain in my elbows as well. One doctor told me its tennis elbow. I haven't had xrays but they have checked and checked and rechecked my blood work. Nothing comes back on it. However I did ask them to check my tsh, t4 and t3, all thyroid tests. My t4 is low. So my thyroid is off and that can cause pain in your muscles and joints.

Im curious to see answers. I also have that kind of pain. A deep ache.
