I breastfed two babies and got a lot of clogged ducts with the first which it sounds like you may have. It definitely makes sense though to go to the doctor and find a lacatation specialist that can actuallly look at you and see what is going on. For clogged ducts a baby nursing is a lot better than the pump-although sometimes I would pump the problem breast while the baby nursed on the other breast because it helps the milk flow. Then massage around. After awhile you can discover which parts of your breast flow out of which ducts, notice where any hard spots are and sometimes see a white spot on the nipple where it is clogged. To avoid them in the future I learned to nurse baby on one side until it was completely soft, burp baby, then offer the other side. Often mine weren't at all interested in the other side but regardless of how long they nurse on the second side-offer the second side first at the next feeding and do the same thing-feed off that breast until it is totally drained. Alternating breasts (every 10 minutes or so) works when you don't seem to have enough milk because it keeps stimulating them, but when you've got plenty and you're not getting them adequately drained it doesn't make sense to encourage over production. Also don't wear tight fitting or underwire bras and don't let yourself get too run down-these things all contributed to clogged ducts for me with the first baby. Also I wasn't real comfortable nursing in public so I'd find myself nursing in uncomfortable places like in a changing room, cramped in the car or even a bathroom stall-none of which helps with relaxing and getting the breast drained real well. It was better for me to hold off on those kind of outings until the nursing had become well established. Anyway, I hope you get some advice that helps and stick with it because it can be so wonderful when it's going well.
