or... Can tinea cause mrsa? I never borrow razors or towels etc or make contact with others but it seems I caught something weird at the local swimming pool.  I got a severe form of athletes feet about four months ago (tried ALL over the counter meds (6or7 from local pharmacy) as well as vinegar foot baths and tea tree oil, taking vitamin c and astragulas. My hand got a bit itchy once - probably from touching my feet when applying medicine. then a mrsa like pus filled boil developed there on my hand . Then the fungus itch spread to the groin area. Then two mrsa like boils appeared above the groin but below the belly button - one in an old scar and another boil five inches away. They made bumps and oozed pus and the skin became pink in a wide circle. The jock itch eventually receded using a regiment of over the counter anti fungal and vinegar and oregano washes and the boils went away afterwards with constant application of mecuraclear (Benzalkonium Chloride) oregano oil and manurka honey, but left red marks on both my hand and groin area. The athletes foot is still with me but is almost gone - and no longer itches but hurts a bit and has small craters between my toes but the skin gashes seem to be getting smaller - hurts but no longer itches. Recently after applying medicine to my feet with my fingers I accidentelly touched my kneecap with my finger. Weird but then very shortly afterwards a mrsa like boil appeared there (I still have it) but no itching occured. It is a red sore lump on my kneecap that ocassionally creates a pustule - the skin is red around it for a diameter of about three and a half inches and the muscle near it going up my thigh is sore. No itching, just sore. Im treating it as I treated the other boils.

Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. Yes, secondary infection in Tina infection can cause MRSA. I advise you to do your blood sugar and HIV test done as it can cause such a severe fungus infection. In usual persons' immunity can prevent the further Tina infection to spread. If you are having some favorable condition than only such severe infection can be spread. I also suggest you to get MRSA test done. Please do swab from the infected part and get its culture and sensitivity done. In case of MRSA testing by this method can help you a lot. Please maintain good local hygiene and optimum blood sugar, as only this much can cure half of your problem. Please wear cotton clothes more as this can have low infection potential. I will be happy to answer your further concern on bit.ly/ Chat Doctor. Thank you, ChatDoctorInfectious diseases specialist, ChatDoctor.
