I have little greenish bumps on my thump for 2 days now the first day it really hurt but it has not hurt much since then. however they still there?

Likely a paronychia: Paronychia is a small pocket of infection at the cuticle area--as pictured here. Usually it is quite painful at first, but as the infection/swelling worsens, the tissues begin to die and pain actually can subside a bit. It is simple to treat with a little incision--using sterile blade/needle. Warm epson-salt soaks can often open up by itself. If worsens, consult doc. Good luck.
