dental abscess
"I have had a severe tooth abscess which I fought on and off for a few years. Last time I had it, it gave me  the most severe pain I have ever experienced in my life! Half of my face was swollen, I couldn't eat or sleep. I would stay up all night crying due to the extreme pain. I was prescribed amoxicillin and ibuprofen. Took them for more than a week but they didn't seem to do much, and the swelling was getting worse. Then the dentist prescribed me metrodinazole along with the antibiotics I was already taking and it changed my life! The pain was completely  gone within less than 24h and the swelling went down within the first 3 days! I have personally not experienced any side effects and would take this medication again if needed."
