breaking out real bad on my arms

I've been on Amoxicillin for a year now and it has been the only med that's ever worked. I've tried a bunch of creams and pills and this seems to be the best way to go.
what is b-5?

if its a prescription...i cant do it...i have no health insurance...any over the counter products you guys know of?
It's a vitamin. Vitamin b-5. aka Pantothenic Acid. It's available at GNC, and maybe at a local drugstore or something. Fairly cheap. If you do a search here on it, you'll probably find all you need to know about it.
I love Tea Tree Oil for helping to clear up the skin. You can dab straight tea tree oil on or I'd suggest picking up a tea tree body scrub as well. Witch Hazel is good for clearing up the skin as well.
Try exfoliating your arms everyday, and or change soap to an anti bacterial for your arms

I had the same problem and the exfoliating (scrubber sponge) got rid of it
You could try tea tree oil 2-3 times a day
