Hi I'm 19, Male and 71 kg, my max bicep curl is 19 kg for 3 - 5 reps, but whenever I lift that weight I feel sharp tingling poking pain in my forarm extensors but not in a way that hurts very bad it feel like it's stinging, I mostly get the pain in the middle part of my wrist and it really hurts when I lift heavy. I'm able to do 17kg wrist curls for many reps but my wrist struggles when doing bicep curls

how do I fix this?
