Metronidazole
"Gum abscess ,new dentist proscribed metronidazole. First day I took three as  was advised. Sweating, feeling tired, depressed and irritable , thought this was just part of the process after a bad tooth and gum issue. Day two after another sleepless night and the symptoms got worse. Severe swelling to the face up around the eyes and also very little pain relief. Thought it was part of the process but by god it was miserable.Not hungry, unsettled bowels etc.This pain did not let you sit down, I had to walk around the house for three hours after taking this medication. Again, I thought it was part of the process.Another sleepless night. ( I was taking paracetamol and anti inflammatories too) Day three ,stopped,still in pain."
