I was observing a pimple on my right breast from 4,5 days. It was looking like a mosquito bite so i thought that it will go away but it\'s still there. I searched about acne and i came to know that its cystic acne. I\'m not sure but the symptoms and appearance was same. Although I\'m not having any pain,itching or rash but still I\'m worried about it.As in this situation I don\'t want to go any hospital. I\'m also breast feeding my 18 months old. Please tell me that it\'s harmful or I can wait for some time to consult a dermatologist. As it\'s on breast that\'s why I\'m scared. I\'m also attaching the picture. It\'s same as a size of pea.
