I'm a bit concerned because I've been experiencing some discomfort in my breasts lately. There's this off-and-on stinging pain in both breasts, and they feel kind of heavy and sore. What's weird is that when the stinging pain hits, I also get this painful pulse on the right side of my head. I know I usually get menstrual migraines, but I'm not near my cycle right now. Could these things be related, or is there something else going on?
