<s>[INST] I went to my dentist Tuesday who said I have an infection and need a root canal on tooth number 19. I started an antibiotic that day and much of the pain has subsided. I go in on Monday for the root canal. I have also noticed that my left pinky and ring finger feel slightly numb and probably have now for about 2 weeks. I was in a lot of pain before seeing the dentist, but I assume the antibiotics are helping with that, plus I was prescribed Vicodin . Is the numbness in my hand related to my infected tooth? I am assuming it probably is. Btw, I am 30,w,f, with no health problems [/INST] Hi, No dental infection or root canal treatment cause numbness of any parts of body. But Vicodin, that contains a narcotic analgesic will frequently reported to cause numbness of extremities ( extreme parts of our body, i.e. hand and feet). Well this is not a major problem. It should subside maximum within a couple of weeks after you discontinue the medicine( Vicodin). Thanks. </s>
