I ve been having numbness on the inside and right under my big toe on my left foot. I m on the couch most of the day on oxygen. I do have muscle spasms all of the time. I hurt the nerve in my tail bone years ago. I was in a fire where I worked could not see how to get out a glue drum blew up behind me and threw me flying 100 feet out the door. I ve tried shots nothing works so we are trying to handle it with meds
