My boi had this nasty LONG spot on his shoulder that was looking angrier than a hippo hernia.
When i finally got a look it had several white heads going along it. Even after popping them all it still didnt clear up for weeks. Normally after i pop them and get all the gunk out the heal up within 24 hours.
All it did was bleed alot and seep amber coloured stuff. Not sure..if thats more of a boil...*thinks*
