What is the best self care treatment for minor cubital tunnel syndrome in left arm ?

Cubital tunnel: Avoid sleeping with the arms bent at night. Your last thought before falling asleep should be keeping with your arms down by your side. Use a headset or a blue tooth device when talking on the phone. Avoid resting the elbow on a hard surface and drive with your left hand at 7 o'clock on the steering wheel instead of 10 or 12 o'clock.
