bacterial infection
"I'm on day 3 taking Clindamycin after needing a root canal on an absessed tooth. I wasn't feeling any pain before the root canal so I don't know how effective this medication is at getting rid of the infection. But, just like a previous commenter, I woke up the day after starting it with flu-like symptoms: Headache (which I almost never get), joint pain, all over body soreness, lightheaded, chills, and pain when I move my eyes. Same story - I called the Endodontist that prescribed it and they said they don't think my symptoms are side effects of the meds. I want to clear up the infection so I'll keep taking it but if I have a choice I'll never take it again. Strangely I haven't had any of the tummy issues most people have had."
