bacterial infection
"Had an old root canal that was giving me so much pain. Went to dentist and they did an x-ray. Dentist prescribed Clindamycin HCL  300mg every 6 hours until gone. So it is about 7 days worth. It totally fixed the pain and infection. However the side effects of diarrhea, headaches, weakness, fatigue, lost of appetite, dehydration (if you don't drink tons of water) was not worth it to me. I've learned that an antibiotic prescribed needs to be discussed with the patient for side effects first!! My physician and yours should also discuss how to ride the waves of the side effects and monitor you. You may decide not to take the antibiotic and want to try something else. This should be an informed choice that you make with your doctor as a team."
