I literally don't know what to do anymore

So, I have never been able to use tampons. They have always given me UTIs, bladder infections, etc. I just always used pads. Well for the last several months, I have been getting rashes on my inner thighs and other very sensitive areas. At first, I thought it could be soaps. I haven't changed brands or used anything that I haven't used before so, not that. Then, I figured that I should change my pad more often. Even tho, I change them very regularly. I can't stand to feel wet. Bleh 😝 anyways. Turns out that's not it either. Crazy thing is, the day my period is over and I throw away my last pad, after a few hours I notice that everything is starting to feel better. Lots less pain, but my question is, if I can't use tampons and pads, what in the hell am I gonna do? 7 months of this shit is more than I can stand.
