I'm sorry to hear about your struggle. It can be very
embarrassing to wear absorbent products (adult diapers), but the truth is that
they are a medical aid just like a cast or a sling work for a broken arm.
Menstrual pads are designed to absorb vaginal discharge and menstrual blood.
Products that are designed for incontinence are specifically designed to absorb
urine, so you'll have much better luck using those. There are both disposable
products and reusable (cloth) products. They both have different advantages and
disadvantages. Factors to think about when deciding between disposable and
reusable are cost, convenience, environmental impact, and health concerns such
as your rash. I'm not quite sure what exactly your rash is, but I know that skin
breakdown is a big problem no matter what kind of products people use, because
whenever skin gets moist it can start to break down. To help alleviate this
problem, make sure that you change your products often, and look into using a
lotion that is specifically designed to help the skin. Different products are
made differently, and of different materials, so while you may find one product
uncomfortable, another product might be fine, so keep looking until you find the
right thing for you. Best of luck!
