I have been having chest pains for going on three years now. I've had chest x-rays, EKG's blood work, back x-rays, stress tests, and multiple MRI's, all of which have been negative with the exception of a Charri Malformation, multiple bulging discs and degenerative discs. The doctors have ruled out my heart, asthma,and blood clots but I am still having pains. The pains vary in intensity, frequency, and duration but have been so bad that I have curled up in a ball and not able to move. Recently my back has began to hurt and I've had tinglingand burning sensations in my hands, arms, feet, and thigh. I am at a loss, does anyone have any ideas on what could be causing my pain?
