Is it keratosis pilaris on the legs? I'm curious about treatment methods for keratosis pilaris.

My legs started to feel bumpy to the touch, and at some point, the bumps spread quite a bit. I tried changing my cleanser first. I wondered if it was because I use a towel to scrub daily, so I replaced the towel with a soft shower puff, but it didn't get better. After searching online, I found out it might be keratosis pilaris. Should I go to the hospital? It doesn't particularly itch or anything, but I don't like how it looks. If anyone has experienced similar symptoms, I would appreciate any helpful information.
