Good for you. When I had migraines, I was in so much pain I repeatedly banged my head onto the wall until it was bleeding and then kept going until I was too tired. Then I would sit there and cry silently because my vocal cords were spent and breathing made my head hurt, until I reached postdrome.

I don't know what point you're trying to make. If you think this is a pain tolerance issue, I don't think you know how pain works. Consider this, people experience pain subjectively and you can't 'see' how much pain they are in because it's not measureable by any metric, let alone facial expression. The 1-10 pain assessment chart is the biggest joke in the chronic pain community.
