Stretch your hand bending the fingers backward. Put a couple of strong rubber bands around you finger tips and practice opening your fingers. Practice a slow cadence on tricep exercises with lighter weight with a full range of motion.
Certain tricep exercises don't bother my elbow region when it acts up. This is just me. Dips, straight bar tricep extension; D handle reverse grip pulley push downs; narrow grip bench and two hands single dumbbell with moderate weight sitting tricep extensions behind the head.
Tricep exercise that hurt like hell are skull crushers, single dumbbell behind the head extensions, rope push downs, and tricep machines. What I'm trying to say is maybe there are some exercises that won't irritate your situation.
