Clogged ducts

Anybody with good information on these nasty things??? This is my first time successfully breastfeeding and I’m almost certain I got a clogged duct in my right breast. It started to go away and then started hurting again. I’m trying to figure out how long it will last how to ease the pain and what to do about breastfeeding because it’s so excruciatingly painful to feed my beautiful son off that breast. Any help would be greatly appreciated!!
