Wrist and Forearm stretches.
Place the back of your left hand in the palm of your right in front of you and then gently straighten both arms. You will feel a stretch on the outside of your left forearm up toward the elbow and possibly in the wrist. Hold this stretch for 30 seconds and repeat on the other arm.
Next, straighten your left arm in front of you with the palm facing up and take hold of your fingers of the left hand by crossing the fingers of the right hand at 90 degrees to them but with the thumb underneath. Your right forefinger should line up with the start of your fingers. Now, gently pull the fingers of your left hand backward toward the back of your wrist and hold for 30 seconds before swapping over and repeating on the other hand. You will feel a stretch at the wrist and the upper part of your forearm toward the inside of the elbow.
Repeat on other arm as required.
Some gentle ice massage will often be helpful if there is any inflammation or irritation to the tendons. Use the ice massage until there is nothing left of the large ice cube. This can be done at the wrist and the elbow.
