<s>[INST] my left shoulder hurts like a toothache. in fact it hurts so badly that i can not tell if it is my shoulder or my tooth. the pain goes up the side of my neck and shoots across my breast. i even have a ringing in my ear. any idea what the problem could be? [/INST] Hello, Could be a muscular-skeletal or pinched nerve. However, we should rule out possible: - cardiovascular event - bad teeth - Labyrinth syndrome So, better get checked by your caring doctor first and run a series of diagnostic tests before deciding for the best treatment strategy. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Albana Sejdini, General & Family Physician </s>
