Hello thought i would try this to relieve some stress...I had a lump right underarm,Got big as a walnut under skin,in about 4 days,I went to ER and they said it was probably infection and had to drain pus,ok did that gave me strong bacterial antibiotics,the next day it filled up again with I guess pus again...its been only two days of antibiotics but am really nervous why it filled up so quick again..should I wait 4 meds to kick in more or is this something I should go to ER again two days later..has anyone ever had a underarm abcess come back so quick or is this normal??very scared of something more serious...please any advice...Thanks.....
