I had something similar when I first developed fibro. It felt like I had banged the nerve (funny bone) and had shooting pain down into my hands. This happened with both elbows and stayed that way for two weeks. Finally it settled down but both of my arms were extremely weak. I remember trying to get food from my crock pot to a platter and spilling the whole dinner on the floor because my arms were too weak. I stood there and cried.
So, this sounds kind of like what I had and it has totally gone away. So, take heart. My doctor put me on ibuprofen with food at the time and I've been taking that ever since.
