12 days ago I was eating potato chips. Bit one on my back bottom molar which has a large cavity in it and felt a brief shooting pain that went from the tooth into the gums. The next day, felt intense pain like a stabbing, burning, swollen sensation in the left jaw and muscles and the back of my gums, although there was never any actual swelling, redness or inflammation-just the feeling of it. After a lot of ice and ibuprofen, I went to the dentist 2 days ago. There was no signs of abscess or infection on the x rays and no signs of inflammation. The tooth itself still does not hurt. The morning when going to the dentist, the pain finally started to recede but upon waking up in the morning my body felt very weak and tired. Even after getting about 7 hours of sleep last night ( waking up about three times), even with no more jaw pain, my body is still tired. It's as if it feels like it's still responding to the intense jaw pain even though the pain is gone. Is this because after 9 days of pain and interrupted sleep, my body is experiencing some sort of release? No headaches, dizziness, shortness of breath or anything else. Again, no signs of infection on x rays. I just feel like laying down and going to sleep, but it's hard to actually fall asleep. Any help would be appreciated.
