My name is josh and i am 18 years old. About a year ago me and my mother were in a rear end auto-collision. The effects were common to whiplash injuries. I didnt feel anything that day but for one to two days after i had awful headaches and took advil. Eventually the pain subsided and i figured i was back to normal. About a month later i started developing large muscle knots on the left side of my back accompanied by numbness surrounding them and sudden surges of stab-like pain in the top of my head. I went to a neurologist who took xrays and when he didnt see anything sent me to a physical therapist. The therapy removed the knots but somehow the neck and back pain worsened. I went to my primary physician and due to the fact that it had almost been 3/4 of a year past an accident and i had not received even a diagnosis he was skeptical and seemed to be trying to infer that i was blowing it out of proportion or even making it up. I went back to my neurologist who sent me for mris which also came back negative and he suggested i go to a chiropractor. Unfortunately, my mother tells me she has similar pain and she went to a chiropractor and it did nothing for her. Recently, my pain has moved to my shoulder/left rib cage, and the left side of my chest. My arm, chest and back switch between numbness/tingling and sharp pains. I am afraid because of the similarities in my symptoms to that of heart attacks. I feel like im out of options. What should i do?
