How to make the pain go away! Help!!

Okay y’all this is tmi but if any of you take metformin you know what I mean by I’ve been in the bathroom alllllll damn day. I just had to up my dose and it takes a few days for my body to adjust. Anyways my ass is rubbed so raw from being in the bathroom all day and it hurts!! Is it safe to use like Neosporin or something?!
