Advil, Ice, personally I would avoid using "bandITs" or forearm bands. Long story short they are crap. Get an elbow sleeve, neoprene would be ideal. Don't wear it too tight.
Bruins Fan posted a good link for exercises. I would avoid doing them until you are healed up. No point in making an injury worse.
Also, I would be so quick to diagnose yourself with an injury. I "thought" I had tendinitis years ago turned out to be a small tear in the lateral head of my tricep. Not trying to sound like a big "Dik" there but you get the point.
As said before try and stay off of it, keep it iced take some NSAIDS and rest. It ultimately is your decision on what to do. But I would honestly seek medical advice before anything. You may have something serious, or you may not.
