This is quite a long question. I would like to start by sharing my symptoms and experiences. This all started about a year ago. The very first time I awoke to a numb leg, but did not realize it until I fell when I got out of bed. I wasn't too concerned because everyone sleeps on their limbs occasionally. Well, this began to happen constantly. By constantly, I mean multiple times a night. Sometimes my right arm and leg, sometimes the left, sometimes one or the other. For the most part my numbness was experienced on the right side. I began to feel strange tingling, cold sensations in my extremities. At times I even felt numbness on the right side of my face. During this time vision in one of my eyes became blurred. I have always had 20/20 vision and all of a sudden I needed glasses for one eye. These symptoms seem to come in waves, extremely bad at times and others not so bad. I went to the doctor and had and MRI and CAT scan. Nothing was found other than the fact that I have small nerve openings, but no stenosis. A few months later I got a herniated disc. Went to a great back doctor. He did not see any relation to my back injury and this numbness/tingling. The neurologist I saw made me feel as though I was a hypo and stress was causing these issues. I cannot accept this, but have not pursued it because I do not want to spend the time or money looking for an answer. As of right now, I have an appt with a chiropractor because I have no other ideas. I am hoping that she will be able to readjust my back. I just cannot figure out how all of these different nerves might be getting cut off, or that it is due to poor circulation. By the way, I am a healthy 22 year old, eat right, exercise, etc. No other health problems other than this.
