Cephalexin Monohydrate and red dots

Was prescribed cephalexin (Kaiser) for a broken skin infection on my leg from a sporting accident. It was pussing and not healing well. Started taking cephalexin immediately after leaving the pharmacy. Within a couple days, my skin infection was not any better. Hives and bright red dots appeared on my chest, my arms, and my legs. Itching was intense - I couldn't sleep - would wake up in the middle of the night totally on fire - but I was told to stay on course by the nurse at the pharmacy and finish the bottle as I wouldn't want an antibiotic from losing its hold on the stronger existing bacteria. The hives, in the form of red patches, bumps, and streaks were visually traveling through my body and hives would break out. I resisted itching. Then one morning I woke up and my entire chest had a huge patch of hives taking up the entire space between both nipples and from the top of the rib cage to the collar bone. It was ridiculous. One week in, I called my doctor and went in for a check up. Instead of prescribing another class of antibiotics, my second doctor (and opinion) opted to stop taking the medicine all together. He determined the hives were an allergy to Cephalexin.

I am taking Cephalexin 500mg/4x per day. Today is my 2nd day (5 more days to go) and I have tiny red dots all over my legs...it itches......and my arms and back and scalp itch too!

Also, last night, after taking my 3rd dose of the day, my stomach started hurting, I started feeling quesy and my hands started shaking. Have you ever taken a vitamin on an empty stomach (especially a prenatal vitamin) and felt nauseated and maybe even threw up because of it? Well, that's exactly what it felt like. I did end up vomiting and my (pls excuse the grossness) vomit was green. I still had no idea what was causing all this. It wasn't until I came on here today and read all the posts that I realized that all my symptoms were due to the Cephalexin, which are green capsules!!!
