I had a MRI and found out I have a sphenoid mucucele. I saw a specialist yesterday and he prescriped steroids, nasal spray and Clindamycin hcl. After getting home and reading the warnings on the Clindamycin, it says that it that it can cause a severe condition (Clostridium difficile associted diarrhea. Should I be taking this considering I have other stomach issues already, Gastristis, Mild diverticulitis, and my family doctor seems to think I have IBS and I recently had to polyps removed. I'm really scared to take this considering the risks and the warning saying symptoms of this condition may not show up for months after you finish the medication. My doctor is out this week so I can't ask her. How safe is this medication, and is there something safer that can be prescribed?
