sinusitis
"I don't usually post reviews but thought I would share my basically good experience. Taking 300mg every 6 hrs for maxillary tooth (molar) and sinus pain - doctor and dentist were not sure if sinus infection or periapical (an acute or chronic inflammatory lesion around the apex of a tooth root which is caused by bacterial invasion of the pulp of the tooth) abscess. (Clogged sinus, pain in face and upper jaw, fatigue, squinty eyes, foul tasting drainage)  In two days pain was virtually gone. Very few side effects - BUT - be absolutely sure to drink lots of water (at least 8oz) and don't lie down for 15 minutes. Now on Day 7 or 8. My stomach is a little bloated more than usual, but bearable. Fairly normal bowel movements once a day. I should also mention: 1) Wake up with bitter taste in mouth - but it goes a way - not a lingering taste. 2) Pharmacist warned of sun sensitivity - I have not experienced that yet, but being cautious. Now started taking Sacchromyces boulardi 5-10 billion units - recommended as a probiotic for Clindamycin in particular against C Diff."
