I took omnicef for about 8 days for a sinus infection. Noticed my left hamstring was hurting. My Dr & pharmacist both said this isn't a side effect for this drug. I took it for a few more days, then stopped because of my leg pain. They checked me for blod clots & it was negative. 3 days after stopping this drug, I still have the leg pain & I'm convinced it is from omnicef. I'd like to hear from anyone else who has had this problem since the Dr's think I'm crazy!
