I have had this problem before...  I am 63 yrs. old. I have moisture in the crack between butt cheeks. Many years ago I had a bacterial infection in this area.  I want to prevent an infected, uncomfortable lump from occurring.  As a child, I developed a rash from penicillan.  Im sure my dr. will advise me to take it.  Suggestions?
Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. It is likely to be bacterial infections. I advise you should apply clobetasol, Aureomycin and clotrimazole combination cream. This will help cure all the infections. This cream is devoid of penicillin and won't give you rash. Please maintain 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/ Chat Doctor. Thank you, ChatDoctorInfectious diseases specialist, ChatDoctor.
