Ah ! guys its just a knuckle pad!! Stanaz mentions that they mess with it frequently and rub it and sometimes the skin layers get off and thats exactly what i would do!! all of yall are not alone lol
i used to have a knuckle pad right on my finger too and since i would never stop messing with it it would always be red and look gross
its not anything serious at all! and sorry to say but the only way to get rid of it is to stop touching it. I had the knuckle pad for about 2 years (because of anxiety, i would rub it to calm my self down) and it takes about a year (give or take) for it to go away completely. So there you go! its not anything serious but if youre still feeling scared you can go to your doctor!
