havnt had a hernia, but i had the same thing happen with my tonsils, were the scabs come off. and you just cough up pure blood. i did this on 5 seperate occasions. and lost half the blood in my body (3 quarts or 2.3 liters) worst month of my life, and it took me about 3 months to recover to were i could do phisical activity.
this was prolly the most painfull
but the most embaressing was prolly the time that some unknown number started texting me and asking who i was, so i was jokin around and asked them if they wanted to have buttsex. turned out to be a friend of mines mom.
