I saw the dentist for extreme tooth pain. He did a "partial" root canal- drilled down and then refilled the tooth. He said I had an infection in my gums around the tooth- pus, etc. He gave me amoxicillin (850) and told me the pain should stop within 1-2 days. It has been 6 days of antibiotics and it still hurts badly and feels swollen, maybe more swollen than ever. I live very remotely, and am worried about complications... Please advise.
