skin or soft tissue infection
"I had a fungal toenail infection, went to doctor, prescribed Cephalexin 500 mg cap 2 twice daily. As I have IBS, took it with food to not upset my stomach, 1st 2, no affect but when I took the next two thought I was going to die, I woke up at 2 am with severe stomach pain, nausea, dizzy,  I was draped over the bathroom counter thought I was going to pass out, within 10 mins my hair was soaking wet & had perspiration running down my face and having diarrhea at the same time I live alone,  73 was considering calling 911. next 2 mornings I saw that my gums had been bleeding, not red but dark purplish black, as I have dentures, in was inside and between my teeth, found it can cause gum bleeding. Talked to pharmacy said to stop it. Never again."
