<s>[INST] I have been dealing with constant grinding, popping, cracking in my shoulders and collarbone area for the past month...seems like the left is the worse. i do noticed pretty severe pain and burning type sensastion with movement also. I am really frustrated with the pain and looking for answers. Any ideas? [/INST] Hello, As the pain in the collar bone can be due to the muscle tightness of the throat and laxity of the neck and can be associated with the shoulder muscle weakness too. This can be connected to the changes in the normal cervical spine curvature and needs to be ad Chat Doctor.  As due to changes in the cervical spine curvature there might be pathological changes leading to pain in various forms and adjacent joints. I will advise you to check for the x-ray or MRI of the cervical spine and see if any abnormal changes are seen.  If so, then using a neck collar and basic exercises for the Neck and upper limb as a whole will ease the symptoms. Hope I have answered your query. Let me know if I can assist you further.
