My cousin secretly pierced her belly button and her boyfriend made her take it out when she wasn't supposed to and now her body hurts her so bad she can't sleep she took it out a couple weeks ago the hole is already closed is there anything that can help her besides going to the docter cause if she does that she'll have to tell her family and if she tells her family they will beat her up

If she does have an infection, and the skin is closed over, there is nothing for her to do but go to a doctor and receive a prescription for antibiotics. If she doesn't go to a doctor soon, she could be in danger of falling ill.

I agree with Drew, she needs to go to a doctor asap!
If the piercng has closed over then the infection is trapped under the skin, if she is already feeling sick then it's not good, she needs antibiotics.
