Mild trauma to left breast region while getting down from train ,I felt little pain that time . Then completely forgot about injury though it was not painful . After 3 days it was painful to touch only.after examination there is no lump no hard mass  no swelling no bruises ,no discoloration,It is completely normal ,just touching that one point feels pain,after little message to that area pain disappear for a bit But after sometime again feel pain .though I am  going to gynac tomorrow for the same. But what could be ,how many days it will take to reduce pain.
