I thought I had a bad blister just a few inches above my ankle so I had popped it like I'd do to any other blister but thick white/brown puss had came out with some blood I let it dry but some rubbing alchol and put a bandage over it the next morning it was very elevated big and red . I left it alone for about three days then after those few days I popped it again and the same stuff came out but it wasn't as big so I put more alcohol and put a bandage and sock over it . I popped it a few times today it looks better than it did but it's sorta blue hot and red around it I'm really confused about what it would be I really don't wanna make a trip to the doctors any advice or ideas about what it might be thank you.
