I have little red bumps on my arm...(well not that red any more, but bumps)?

I have these little red bumps on my arms, not underarms or anywhere else.. I googled it and apparently its called like Keratosis Pilaris and it like this common thing, your body produces too much Keratin and your hair gets trapped in its follicle or something, I heard there is like no known cure and I've been to the doctor too. I've tried not using moisturiser for like a month, then I used baby lotion, baby oil, Vaseline, cream, a loofah, exfoliating with body scrub, a pumice (clean one), when I leave it alone for like a week it just stays the same. I don't pick at my arms and I don't wear tight sleeved clothes.... is there anything else I can do for it to go away? I've had ti for two years. Does anyone else have it? I can't wear tank tops anymore, I've tried waiting for it to go away. I even tried applying a hot wet cloth on my arm for a minute then applying a cold one afterwards to do something with my pores. Any suggestions?
