Buttock blisters

I have recently developed 3 blisters in the crack of my buttocks which i assumed was from sweat or wearing thongs for years but they are so painful i can't lie on my back in bed, i have tried sudocrem and canestan cream but nothing helps. I know it's not an STI.

Hello,
I cannot confirm anything without examination but it can be due to moisture(due to sweating or frequent washing), the abrasion caused by clothing,the pressure of sitting,chemical irritants like sopas, toilet paper and skin conditions like fungal infections, seborrhea or herpetic blisters.

I suggest you to get an evaluation done from a dermatologist as the treatment is different for all. Till that time, wear cotton clothes and take some Benadryl if there is any itching.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
