Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. It is likely to be bacterial infections. I advice you should apply clobetasol, neomycin and clotrimazole combination cream. This will help cure all the infections. This cream is devoid of penicillin s and won t give you rash. Please maintian good local hygiene by frequent cleaning and mopping. Avoid extra sweating in this area. You can wear cotton undergarments. This will absorb the extra sweat and help cure the problem. Loose fitting garments can help give good ventilation and prevent sweating. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
