Hi, just to add a possibility, as we are all detective's! Figuring out what is going on,..
Have you tried a chiropractor?
I have to go often. Nerves come from the spine.. I think ice pick pain is sometimes! a nerve type pain.. I used to say I have a knife in my neck and one in my eye.
It seems doing a variety of healing methods, and medicines can help us.
I'm going to my first rhematologist in two weeks, hopefully getting diagnosis. My docs are so not helpful.
