My tutor(like a mummy to me) and my cousin had theirs removed. They were in A LOT of pain too. Infact, my tutor got an infection, but she was back at school within a week! She's amazing and had to be there for our leavers day(last week). My cousin recovered and is fine now as is my tutor (in progress I'm assuming still as she only had it 2 weeks ago).

Have you been given any painkillers? Could you get any if not?

Make sure you treat yourself well and keep relaxed.
It'll be okay.
