nipple soreness from pumping

I have been slowly getting nipple soreness from expressing milk. Is there any way to reduce the soreness? I have been trying size 21 and 24 flange but it still hurt. I cannot tell if the flange works properly or not. TIA

Lower suction power, or if want to give nipples a break to recover, can hand express for the time being
