Metronidazole
"I'm done with the first day of meds and I feel horrible. I got prescribed Flagyl (500mg 2x a day for 7days) due to having a Bartolin Abscess. Prior to the medication, the only symptom I had from the abscess was extreme pain where the abscess is located. So far, I have felt extreme fatigue, extreme headache, nausea, & sour taste in my mouth. On the bright side, the area where my abscess is located still hurts but definitely not as much. I gave it a 10 on the scale because the Flagyl is effective regardless of the worst side effects I've ever experienced. I've been on many different antibiotics before but none have ever made me feel like this. Definitely hoping I never develop a Bartolin Abscess ever again because Flagyl is not fun to take"
