Sakura, I had that happen before. It looked like a murder scene in my bathtub. Of course, I was taking a bath instead of a shower, so I had to drain the water and refill the tub again. I had no desire to wash in my own blood. Good news was that it stopped before I got done bathing so I didn't really have to clean much.
My older brother was prone to nose bleeds when he was on this acne medication. It caused him to bleed at the most random of times. One time, we, as a family, went hiking and he started having a nosebleed. It was a good thing we had packed a lunch, complete with a few napkins because he would have had to stick leaves from an oak tree up his nose.
Don't even be talking about nosebleeds. I get them too. Try to remember vaseline in my nose every night (blows it out in the morning) because my nose is too dry. Now with this new job all the little dusts coming in my nose from the clothes on top of dry air. ugh.
Sakura, how did the pool take-up go?
**eta, good remedy for nosebleeds- shock yourself, run cold water down your back. It stops it so fast!!
