Hello~It looks like you have had a lot of test done. If they did not do one for lymph cancer, you might want to ask for it. However, everyone of your symptoms point to a pinched nerve, and NOTHING but a chiropractor can help that,. When our nerves in the neck and upper back are "out" or pinched, they can cause all kinds of visual problems, head ache, pain in the arms and side, you name it.
