I thought I just posted but don't see my response :(
Sunshine-
It's been a while since I've posted here but wanted to let you know I recently experienced the vibration in my breast as well, freaking me out of course. I have suffered on and off nearly 20 years with health anxiety and panic attacks of various forms and phases over the years. The doctor thinks the vibration may be hormonal because I notice a lot of my symptoms every two weeks at ovulation and when my period starts, joys of getting older? idk....however, also I have been experiencing reflux symptoms over the last several months and the doctor said it could also be related to that. Hmmmm. who knows but something to think about! Let us know what you find out!!
