Is it to low? Nipple pircing

When I got my nipple Pierced I didn't know if she did it wrong or not, I felt like one was lower then the other but figured maybe one of my nips was just bigger then the other, but it's been 4 weeks now, the pain from getting them done is gone and the left one feels fine, but the right one hurts constantly, the jewelry keeps leaving an dent in my skin and it feels like it's crushing my nipple, d I need to get it re done or just get a bigger bar?
