Advice

My gf deals w serious anxiety, she has had a pain in her boob and she said it kind of makes her feel like a pukey feeling when she feels it, she said she felt a lump, but now she doesn’t , I felt it for her and felt no lump, but it’s a on and off pain, she got off her period yesterday, but she’s felt the on and off pain for a few weeks. Any advice? Is this normal at all? No weird textured skin or discharge of nipples.
