Glove hand constantly getting stung and bruised

Stop catching on your palm helps as well. You maybe tipping your catch forward bringing the basket more parallel to the ice, which is causing more pucks to hit your palm. Try keeping your wrist bent back, which brings the basket to the vertical, also pulling your elbows in tight to your sides will aid in this as well sealing you up tighter.

As an interim fix, you can use a TPS Goalie inner glove. That will help reduce the stingers some. Weightlifting gloves with padded palms also work.
