I have a blister at the bottom of my butt that's been bothering me a lot. I think it's from friction from my new jeans. There was another blister on the other side but it's mostly healed at this point.

The one that's still bothering me has been there for about 3 weeks. When it's really bad and painful to even walk I'll drain it (with a sterilized needle), put neosporin on it, and cover it with a band-aid (I shaved the area to make it easier).

After it gets better I don't worry about it but then it gets bigger again after a few days. I'm a runner so the area gets a lot of friction.

Should I keep the area covered even when the blister is healing? Does anyone have any other advice? It's only been a few weeks but I'm getting really tired of dealing with it.
