...def not mastitis. It's only tiny on the tip but the pain is phenomenal. It's been hurting for 2 weeks, turned yellow, the tiny bit where it is doubled in size, now black with I think yellow behind (sorry, sorry...) which is when the pain went through the roof. Just back from the out of hours GP who's given me volterol but doesn't know what it is and is sending me to see a consultant surgeon tomorrow. Has anyone had this? As on the other recent thread about blocked ducts, my bra wearing did change...I started wearing underwired and non-wired sports bras a few weeks ago as I was planning on stopping feeding, but didn't stop...and now only feed twice a day...have an inkling this may not be unrelated...
