Neuropathy

I have been told that I have neuropathy but, I also have fibromyalgia which also gives me the same symptoms. I have nerve damage I have been told, and I have a pinched nerve in my lower spine. I had a severe attack a few days ago along with a fibromyalgia attack, and as a result a nerve went down my rear end all the way to under my right foot up the front of my right leg and hit a nerve and rested itself there like on a muscle or a bone. The pain was awful and my doctor had to give me a trigger point injection.
