Im a girl of 19. Im a computer engg student, a dancer and I sometimes do yoga. Ive been suffering from a pain in the left side of the chest and left arm from many weeks, which got worse recently.Im not able to hold anything easily with the left hand. Im not able to breath normally. Every time I breathe in and out, Im having a stabbing kind of pain in the chest and at the same position at the back, from my left shoulder till the fingers. Its even terrible when I force a deep breath. The pain is the same whether I dance or not. I consulted a chest specialist, got my ECG, Abdomen scan which showed normal. But a chest X ray showed "Hypertrophied C7 transverse process bilaterally". He said it might be an over growth of a bone, the pain might be a variation of spondylitis since I had no pain in the neck and asked me to go to a neurologist. The neuro surgeon asked me to get X rays of the neck, and said everything is normal and just not worry. Im finding it difficult to sleep at night as I cant find a proper painless position for my arm. Im not able to do any poses for yoga.Are these symptoms for TOS? Which specialist can I consult for it? Please help me
