I Gave My Girlfriend Chlymidia. We Both Got Treated For

I gave my girlfriend chlymidia. We both got treated for it but after she still had a smelly discharge a lot of it . she got feminine products to help with that it worked for a while and now she found a lump of a yellow substance near her clit . I don't have any symptoms and we had sex a few tomes after we both got treated . And we haven't had sex with anyone else since. What do you think is the problem
