Good for you for writing your question candidly! It's not always easy to discuss personal issues openly. Thanks to CureZone for their numbering system!
My problem was on the more sensitive skin of the entire external genitals. Swelling was a problem, too, which was noted by some of the posters I read.
Urine stung mercilessly.
I wrote a list of 20 or 30 possible causes, and tried a number of natural ointments/washes. None of them worked, some stinging instantly.
Then a healthfood store worker suggested three products.
Open a capsule of Acidophilus & Bifidous (mine was Natural Factors - double strength), with dry fingers, and sprinkle the contents into a basin of warm water.
Add 5 drops of Grapefruit Seed Extract (not grape seed), (mine was New Roots) and mix into the water a little.
Then lower the area into the basin, and wash the affected skin.
A 'sitz bath' isn't really graceful to behold, but we should all figure out how to manage one. A plastic basin in the bathtub may be a good way, but (don't laugh) I do mine in the bathroom sink, although the spout gets in the way and I have a hard time lowering myself deep enough into the water. (Stop that giggling!)
Anyway, the lady suggested an Aloe Vera jelly be applied after patting dry. Mine was Lily of the Desert 99% Aloe Vera Gelly. It stung something awful, but not as badly as the ailment itself.
I didn't use the Aloe Vera jelly on the second sitz bath several days later. However, relief was a bit slower in coming. The Aloe Vera jelly seems like an important part of the treatment. Next time, if I do this treatment a third time, I'll cut a piece off my Aloe Vera plant and try the jelly from inside the leaf.
I know it's hard, but don't scratch. I learned just to press a little on intolerable individual itches.
Toilet paper is made chemically, and it consists of wood fiber, tiny slivers. Even a cotton facecloth is chemically treated fibers, and always contains traces of detergents. Boy, did I learn to lightly pat myself dry, only!
It's only a guess, but such irritations may come from or be aggravated by sweat. Maybe especially when cleansing toxins. Or, urine.
Anything tight, and sitting, makes the situation worse.
I rolled two large towels and placed them in a V-shape in my computer chair, to raise the area off the chair seat. Later I bought a rubber inflated ring to sit on. (The plastic rings soon develop leaks. Was that you laughing again?)
It takes a few days, but the whole treatment worked for me.
