im 17 and i was laying down one time when my right breast started to hurt..i didnt know why this could be but i did have my period at the time so i figured eh hormones..but then i felt a lump. i made an appointment with my gyno to check it out and he couldnt even find it. he was sure it was hormones..i coudlnt even find it that day either.. but STILL my breasts are both sore all around..more sore spots then others but in general are really sore. The lump is still there and in the same spot and it has definently come back.. by looking at my boobs they look completely fine..no discharge or ugly skin or any symptoms of breast cancer.. im really scared that i have like a million sists in both boobs or something..what should i do about this and should i be scared? im so young..ive never had a problem like this before.
