Numbness / loss of pain and temperature sensory on left side from shoulder blade to toes
I have no idea what is wrong with me. I have no sense of pain or temperature on the left side of my body. Every once in a while my leg will twitch too. It starts from under my shoulder blade and goes all the way to my toes. I had an MRI of my lumbar and it showed nothing. I have another MRI scheduled for my Thoracic area on Satuday. I hope they find something because if not, my Orthopedic said I'll need to see a Neurologist and probably get a spinal tap. He also named a long list of things it could be which scared me a lot. I'm only 33 and I have young children, after that dr's visit my kids' whole future without me flashed before my eyes.
Anyone know what this could possibly be? My face, arms, hands, and shoulders are not affected at all. It's just only my left side on both my front and back, all the way to my toes. I've googled everything I possibly can and nothing perfectly describes my symptoms. I don't have any irregular headaches either.
I just want to know what's wrong with me and having these spaced out Dr's appointments are very frustrating. Anyone have any idea?
