Blocked milk duct

I think I have this I have pain on my nipple just below the actual nipple when baby sucks and when I squeeze it This is the second time.but the first there was a distinct lump just outside my areola. I tried massaging it but then it went away eventually on its own. It's weird, I swear even after my baby feeds on this boob my breast still seems full not sure if that's just me. What should I do to get rid of this? Anyone had one recently? Thank youuuu.
