<s>[INST] I have had pain at the left side of my neck for 3 weeks. This has become worse during the last 3 days with the pain in the left side near my clavicle and also near my scapula and the left side of my spine. The pain is constant and very painful. I can get no relief. I have taken two co codamol (500 paracetamol 30 codeine and 400 ibuprefen). Any ideas what this could be.
