In regards to golfer's elbow; all you can do is rest it and ice it. There is no fancy fix for that injury other than to wait it out.It can be quite a slow injury to overcome as well, so sorry to be the bearer of bad news!!
KK, thye sensation you're experiencing may just be two tendons slipping across each other. Don't get complacent with it though - that could be the straw that breaks the camel's back!
