I had a small puncture wound on the top of my foot .it turned into celluitis. and i had some pus squeezed from it a feq weeks ago.the doc told me to keep picjing the scab when it forms and continue to drain it at home. well,I've never been able to get anymore out of it and now there's a superficial lump there that's painful and itchy.I'm not sure if it needs drained agian or if my body will just reabsorb what's still under the skin?
