What should I do?

Sarah • My life is active, fun and crazy... Trying to keep it as organized as possible!
Breast are really sore, it's been three days now and no relief.
No where near my period, I had a light one on the 13th and 14th of this month and it's very rare my breast even get sore.
A few days after my period I had a light pink/red discharge that lasted a few days, so I think it might be hormones.
 Can anyone please give me advise on how to make them less sore or what I should do?
