I broke out in blisters one time after trying new pads. I went to the ER because I didn't realize what was going on. The doc didn't even do any tests or anything but diagnoses my with Herpes....?????
I was at a friends house a day or two later and had to use stuff she happened to have since I had forgotten to pack mine and the rash/blisters went totally away in hours.
I tried the other pads once I got home and WOW, blisters again. So I knew I was allergic to something in those pads.
I suggest that you look at the label and see if it says "Deodorant" or something like that. They could have just added something that doesn't agree with you.
I used pads my entire life and know that is something that those people who do product development have no idea about. They just do something to a good product to "improve" it and they totally mess it up.
I can't imagine cloth pads being difficult. Other that having to wash them each month then having to sanitize the washer afterwards before doing any other laundry. Women made their own for centuries before we could go to the store and buy them in a nice little package...lol.
