How Should Ulna Bone Pain After A Workout Be Treated?

Hello, Im 22 140lbs and 5'7 recently ive been working out alot. for a small guy im putting up some serious weight up in the gym but have noticed pain in why i believe ulna bone between wrist and elbow. it is a dull ache, and it's of an average pain. Usually occurs when the moment I let go of the weights, and hurts for about 3-5 secs after then kinda slowly goes away
