I am a little concerned I had a mammogram last week and they found a clogged duct. Since then and even before I have been experiencing pain in my neck upper left shoulder and middle region back I also have a pulsating feeling in my stomach and upper left shoulder blade almost like something is moving. Both my breast are tender but they only saw one clogged duct on the left breast. I also just had a baby 3 months ago no longer breast feeding but still have a little milk come out. Also I have migraines and dizziness. Is this something anyone has heard off could these things be related or separate issues?
