I\'ve had a recurring abcess under a crown for abour 6 years now. Sometimes it comes and goes with out much notice, others, like recently, it sends me a world of pain. This time around was the worst. I had sensitivity to lights and high pitched sounds, like cell phones. But if people were talking to me, I could barely hear them. I have a hard time swallowing anything, let alone food, and I can\'t eat anything harder than Ramen noodles as it is. All the doctor can do is give you antibiotics and pain killers if needed. The antibiotics will help the infection leave.
