bacterial infection
"Had an awful infection along my right side of my gum line, including a tooth that was abscessed. I have terrible side effects to almost any antibiotic so I was not very impressed having to take it. I started the medicine yesterday, and drank it with tons of water, made sure I didn't lay down for almost an hour and also took acidophilus. I had no issues whatsoever, however this morning after taking  the first dose I started with heartburn, I've also noticed an odd taste in my mouth. I took Pepcid and hope that will help knock the heartburn back a bit. Seems to have been improvement with the abscess already so I hope this is as bad as it gets. In comparison to the toothache, I'll take the heartburn. Drink plenty of water!"
