OUCH! You have my sympathy. I've had plaurisy a few times, but it was brought on by bronchitis and ashma + having an inflammatory autoimmune disease. I bound when I was first getting boobs; 13-15, but got over some of my shame, but always wore sports bras until I was older. I identify more as Androgyn, but am probably more male in my brain/heart than female. It upsets me that I can't wear tight sports bras or anything like that now, not even a minimizer bra. I have D cups. Ugh. I've developed costochondritis, which is inflammation in the ligaments and tissue between the ribs, due to the autoimmune disease. It hurts. Regular bras hurt if they're not loose enough. I wear camis with a tank bra, but of course, that does very little for support and no compression. It's just not an option for me to compress at all.
Please be careful not to hurt yourselves. For those with chaffing issues, I have psoriasis in some not so nice areas(thanks the to autoimmune stuff again) and I found a product they sell in the South(my dad lives in Alabama). It's called "Monkey Butt Powder" You can find it online. It really helps. I've also found that Desitin- aka baby butt ointment heps with bad chaffing until it can heal. My regimen to keep the bad, irritted, chaffed psoriasis at bay is OTC hydrocortizone cream after shower, followed by "Monkey Butt Powder." In the evenings, after cleaning the area again, I use more hydrocorizone cream, folllowed by aloe vera gel. I know my bad psoriasis isnt the same, but it hurts similarly to the chaffing I had when I would bind. The hydrocortizone helps the inflammation. Just an idea to try.
