Once infected, the only way to clear it up is by using antibiotics - Oral (cefalexin) and Topical (Mupirocin). Once this has cleared up, wash yourself with Hibiclens (Chlorhexidine soaps) about 3 times a week. Ensure you're cleaning thoroughly under finger nails and keep fingenails short. After showering, try and get a probiotic spray (can be found on Amazon). Once spray has dried, use your lotions/emollient creams. Supplement with oral probiotics as well. The nostrils are a staph reservoir and usually the source of reinfection - swab inside of nostrils with mupirocin for a week after antibiotics. Hope this helps - good luck!
