I am 27 years old, married, 2 boys. since 3 weeks I feel pain in my left breast and arm and this pain in almost continuous but becomes stronger in the breast itself about 2 - 3 times daily. The pain comes at any time irrelevant of period or anything else. I did Radiograph, mammography, echo,...etc all was clean. The pain goes only when I take a pain killer but for only 2 - 3 hours. Pls advise me what could be the reason and what do you advise me to do. Thanks.
