wont let me upload image due to file size but it started out as a hard lump and it got bigger so i popped it and i did pull a hair out of it but now its started become a sore. when i popped it red and yellow pus came out and i kept applying pressure and it kept bleeding rapidly!
if its an open sore you should get a pcr test done on it. its highly accurate but you have to get it none while the sore is still fresh.
