I noticed i have purpke spots on my left breast near the nipple. it was itchy until the spots came.

How old are you?: Many ailments are affected by age. So let us know this important parameter next time you ask a medical question. You can wait and watch your purple spots for a few days, see if these will go away once you stopped itching. Keep the area washed up with soap and water couple times a day. If these get worse after one week of observation, get a medical doctor to examine you and offer you some advise.
