Anyone had this? I had my phone in my inside pocket on Thur and Thought it was on vibrate as there was a kind of tingling in the centre of my left breast. Phone wasn't vibrating. Breast was a kind of tingling inside. It has happened on and off over the last couple of days. Not sore. Definitely no lumps. Just a weird feeling. I'm 56, not on any hrt or medication. Any advice? TIA
