I tested positive for strep 3 days ago and have been on antibiotics. my throat still feels like im swallowing razor blades. ibuprofen isnt even touching the pain and its been 3 days since starting amoxicillin?

You may have already formed an abscess or another complication of a strep infection. If you have any lopsided swelling, changes in your voice, swelling under your tongue, fever, difficulty swallowing, or breathing problems, get in to see a doctor immediately or go to the emergency room. If you don't see improvement after a week, return to the provider who gave you the amoxicillin.
