One thing you can do when not playing guitar is to use a splint, its not always posibble but restricting the range of motion helps but as with all things not perfect. On bad day place a bag of ice on the arm affected about 2 - 3 inches from the elbow and let the ice do its job, explain more in email but thankyou for you reply.
People laugh because I'm different, I laugh at them because their all the same. :D
