My husband had stiches on the side of his middle finger about a year ago. When it healed there was a small bump....we thought scar tissue. Over the last couple of months it got bigger. It was very hard, like a callous. Today he pressed on it and puss came out. A large rubbery thing came out of it, it was solid white. No pain, some blood....what the heck was it? He is 38, 5'9, 155lbs....no medical issues.
