Hey guys so I get a super sharp pain in the middle of my right forearm when I do curls with anyone over like 25 lbs per arm.
I've tried so many things in regards to form, speed, range even different movements (incline, preacher, hammer, barbell ECT)

It feels like shin splints and I feel it when in the flexed position until I put it down. Once it's put down I fades after a few seconds.
I've had to come and go since highschool (so about 10+ years)

It's litteraly dead center of forearm

And it's happened both on and off cycle.
