One week back I got three blisters on my chest which I though due to friction and popped it. Next day there are multiple blisters and rashes on the area where my skin folds when I sit. As it was very sweaty in that area I thought these are nothing but sweat/friction blisters and popped them and applied iodine ointment thinking it will help it to heal. Even after one week I still have those painful redness around those blisters and causing discomfort. Attached pic of the blisters with this question. Please suggest how to get rid of this.
