Yup mine have been painful since early trimester, can't shower facing the water I have to turn with my back towards the water otherwise ouchies. I have discharge too, to the point where some days I wonder if I should wear pads as I am having to wash my bras everyday otherwise they smell!! I also get the 'milk coming in twinge' in them as well have had this since about 17 weeks, very odd.

Hope you find some relief though! I have heard of cabbage leaves relieving mastitis pain, maybe it will help you too
