<s>[INST] Went to a dentist in Nov and was injected several times in lower right gum line.  The procedure could not be finished because the area was still suscuptible to pain.  I had about a week of sorness and now cannot open mouth fully without severe jaw pain. [/INST] thanks for your query, i have gone through your query. the pain could be because of the tooth infection resulting in pus formation involving tissue spaces. consult a oral physician and get your self examined. if i am your treating doctor i would have suggested you to take penicillin, metronidazole combination with an analgesic if you are not allergic. consult a physician immediately before it result in any complications like breathing problem. i hope my answer will help you take care. </s>
