My DD has been fussing since we got back from hols a few days ago, and feeding was borderline painful too. It took me until today to realise that she's grown so much we don't need the pillow on my lap anymore, and we weren't fitting together properly to feed well itms? I realised I hadn't been using a pillow whilst away and obviously neither of us missed it. Have dumped the pillow at home and feeding is back to normal - could it be your LO has grown a bit and you need to try variations of your normal positions to accomodate a growing bub?
