I get a lot of pain on my right hand and sometimes in fingers, it gets tense from forearm to the shoulder which makes me get more tire and lose stick control. I stretch before practice.

EJ-MASTER Sounds like you may have carpal tunnel if it was just your fingers alone you might have arthritis in the joints in your hands go to your doctor.

There is a a relaxed method of playing and there are learning videos on the market. This happens a lot to beginners. There are other warm up technique like holding two drumsticks with one hand at each end and twisting them around as to stretching your wrists from one extreme to another. But I think the trick is to practice you rudiments slowly for a few days, then progressing your way up to speed and don't rush it. Get a practice pad, this may help.
Let me know how you do with the relaxed method. I've seen Ginger Baker from Cream and the drummer from ZZ Top use this method. It looks real easy.
Good luck and get back to me on this pain in the hand.
