Hi I cut my thumb quite badly and there is a small, but thick piece of skin hanging open. It has been bleeding a lot non stop for 20 mins through so much cause and I’m putting pressure on it and the bleeding slows, but it is still bleeding through a lot of gauze. I am not in much pain but is there anything I should do? If it doesn’t stop bleeding in next hour should I go to the emergency room? Please help I want to sleep I have an exam tomorrow but I can’t because it’s still bleeding a lot. Thank you.
