Last Thursday, after swimming, i discovered blue-ish veins on the side of my left breast, the area is quite tender/sore, but not to the point where it disturbs my day-to-day activities, i've been consuming ibuprofen to ease the pain, so far it seems to work, although the area still feels tender at times. What do
these blue veins mean
? could they be related to my hormones? Or could it be due to a muscle strain, as it has been a while since I swam?
