Do you get severe irritation from using pads or having an upset pouch? As I got older, I realized that I couldn't use tampons anymore because they were causing irritation and I also avoid using things like kotex pads as much as possible. I switched to a Diva cup and my periods are much less uncomfortable and I have fewer leaks. I would try to avoid any disposable pads and switch to the washable ones if you need to use pads. I can't say enough positive things about the cup vs tampons. It is night and day more comfortable but it is a PAIN to empty in public restrooms and I only have public restrooms available at work (thankfully this is a once or twice per cycle issue). I've noticed that most women complain about their pouches or colons getting upset during their periods so make sure you are keeping yourself as clean as possible and using a cream. I would look into setting up a bidet at home if you don't have one. I carry baby wipes in my purse in case I start to get irritation when I am out. I started using the corn starch baby powder I bought for my daughter and it helps a lot as well. I wash with the bidet or baby wipes, dry my skin, apply some powder using a square of TP, then apply some calmoseptine. If you aren't using it, calmoseptine is a life saver for most people with bowel issues and my husband swears they put some sort of skin stem cell factor in it. The other thing I could think of based on the doctors assessment is endometriosis? If that is the case, you should see a gynecologist.
