I have been playing video games and using computers for several years now and I always have the head forward posture. Lately for the past few months I have been experiencing neck pain, dizziness, slight intermittent numbness, and tingling/cold sensation in my face, shoulders, and extremities. Is it possible that these symptoms could be caused by poor posture? I went to the ER back in January with these complaints and had a CAT scan of my head, and xray of my neck and they said there were no visible abnormalities and that I should follow up with my primary care doc. My primary care doc said that judging by the results of the tests that he sees no reason to be evaluated by a neurologist. They mentioned poor posture, nerve compression, and vertigo as possibilities but I have not yet been diagnosed with anything but I still continue getting symptoms and it seems they are getting more persistent and worse. I'm also having tmj problems and which is causing me pain in my jaw and head. I'm a college student with no health insurance so my options are limited.
