Thoracic Outlet Syndrome/ Chronic chest, back, neck, shoulder pain

Last year I had suffered injuries in both ankles from martial arts and was using crutches for 8 months. Soon after I got off the crutches I began to feel chest pain on the left side with breathing difficulties. At that time i thought it was my heart and went to the hospital. After blood tests they reported that my d-dimmer was elevated greater than 4000. They thought there was a blood cloy. Further testing, CT, VQ, and Ultrasounds of the lower extremities ruled out pulmonary embolism. They told me that it was a muscular pain and it could be chest wall pain. It has been a year and my symptoms have worsened. I have severe neck pain, the neck muscles swell up, there is shooting pain in the chest, the chest becomes inflamed, left arm has a dull aching pain, pain down the spine, pain in the shoulder and there seems to be a lump in the clavicle area but the doctors cannot feel it. I feel it. Now this pain is at a point where its unbearable. I have been to an internist, cardiologist, general practioners, chiropractors, vascular surgeons, homeopathic, naturopathic, physiotherapist, massage therapist, sacral cranio therapy practionner, accupunture, and Chinese medicine. The chiropractor said that he think it is Thoracic Outlet Syndrome as the doppler test showed the left arm velocity increases to 322m^2. I am currently seeing a sports medicine doctor but they said they have no idea and this is out of their scope. I'm in constant pain, cannot do the activities have have enjoyed for the past years. Please provide some insight.
