I keep getting bumpd on my under armd hard like pimple but never comes to head painful?

Underarm Bumps: Can''t tell without seeing. It sounds as if you have a condition called hidradenitis suppurativa. Do see either a dermatologist or your primary care hysician for this. I wish you luck with this, disorder, because it's not an easy condition to cure.

? Abscess: Your description sounds like you have an abscess. This will likely need to be drained to get it to resolve.
