Been on Vyvanse since November to help control binge eating , bulimia, and ADHD . Yep I've had a rough year . So a couple months ago I noticed swelling in left breast. Now it's both and they're all vainy. Sorry tmi.... But I'm Terrified of cancer . I'm getting ultrasound in a couple weeks. Just curious if any of you are experiencing this too. Thank you very much! I and no I'm not pregnant :) and I never experienced this during pms until after Vyvanse. I'm also 33 mother of ) and 8 yr old . Thanks again!
