Hello,
From the symptoms it sounds like a boil or an abscess. A boil caused due to staph infection generally starts as a reddened, tender area. Over time, the area becomes firm and hard. Eventually, the center of the abscess softens and becomes filled with pus. Finally, the pus "forms a head," which can be surgically opened or spontaneously drain out.
Apply warm compresses on these bumps and consult a dermatologist for examination and confirmation of diagnosis. A culture sensitivity of the discharge from these bumps needs to be done to confirm the causative infection and its sensitivity to the antibiotics. Then she needs topical and oral antibiotics. Also get her blood sugar levels estimated because she is getting repeated skin infections.
I hope it helps. Take care and regards.
It absolutely can be staph. MRSA is one of the worst types of staph, and can cause breakouts throughout the entire family. You need to wash all bedding, make sure to use bleach while washing bedding and towels, wash hands frequently, disinfected door knobs and other things the child may touch. DO NOT try to pop the bumps like pimples. This is the easiest way to spread the infection around.
You need to have the sores cultured and sent to the lab for testing. MRSA is curable, but I have seen it get out of hand to many times in patients. A person can have multiple break outs over a period of time, or in during one episode.
Sulfur antibiotics work the best to kill this bacteria.
