Then again, look who we are talking about. I don't believe the Enquirer, but I've always thought it odd that Cosby didn't use his fame to promote gun control following his son's murder. Jesus, that's a low blow even for the Enquirer if they're making it up to sell papers.
In general, there are 4 things you can do for your elbow pain RIGHT NOW. It is a good idea to avoid heavy lifting and gripping to allow your arm to rest and recover. Anything that is causing your elbow pain is most likely making your condition worse and should be avoided.
Partner tennis elbow stretches. The arm should be out to the side, and rotated inwards (downwards). The wrist is then flexed (bent) to increase the stretch. This stretch is more easily done with a partner to help. Hold the position for 30 seconds and repeat 5 times. Aim to stretch at least 3 times a day.
