Breasts are so sore!

Help! I am breastfeeding. My breasts are incredibly sensitive and sore. He is 3 weeks old. I already use a nipple shield because I had a lot of cracking and bleeding from the hospital. I also use nipple cream and soft breast pads to pad my bras for comfort. He latched super well from the beginning but he has a very intense sucking. I talked to the coaches a lot in the hospital so I know his latch is good and he is just strong. But my boobs and nipples are so sore! They aren’t bleeding or cracked because of the shield but even a slight touch to them hurts. My boobs also tingle or throb if it been a while since he ate. I have been paying very close attention to engorgement, massaging often, and pumping before I go to bed since he sleeps up to 7 hours to avoid issues from my coaches advice. They aren’t hard or have lumps so I know it isn’t an infection or mastitis. They just hurt so much. It been making me dread feeding him from the pain. Any advice?!
