Hello. I am a 18 year old white male who has had a year of very strong anxiety/hypochondria so take this in account before answering my question please. Due to a surgery this year i was forced to stay home from school during the entire school year, so i was basically sitting in front of the computer for 15-16 hours a day in an office chair in same position over and over again. I have a severe anxiety of having MS. My symptoms are basically as follows, I've always had neck problems, neck problems which are giving me cervicogenic headaches. What my real problem is, I get burning pain/tingling/heaviness in my legs and arms. Basically it's like burning pain which is accompanied by tingling, however i also have this very, very intense ticklish/tingly feeling around the chest and back as well from time to time, and around the shoulders and scalp, just about anywhere. I am more concerned about the burning pain and tingling in the limbs though. Ok so, I've seen two neurologists, one of them is a MS speciliast. He did a full neuro exam and immidiatelly dismissed MS without ordering any studies. He said my problems come from my constant static posture in front of computer and probably pinched nerves/herniated discs. I did not believe him so i went and had a brain MRI, it was clear, however afterwards i read on the internet that such symptoms would mainly come from spinal lesions and not brain lesions. I am so scared i have it, my burning pain/tingling appears to be aggrivated after long hours of hunched over posture, but i've never had this before and it really scares me. And i also read that herniated disc would not cause all of this in all four limbs. Please can i have some opinions on my situations? thanks
