In reply to Clee: get it iced, rested and checked out, especially if you got a lump.
If you climb with it like that then its more likely to make it worse than better...do you want a break from climbing, or a potential end to climbing (worst case scenario where you aggravate tendonitus repeatedly and end up not being able to use that arm).
I got a bad case of tendonitus from using a wrecking bar to demolish a wall in a confined space last feb, took a long lay off to get back to usual, still twinges as I probably rushed it and started climbing/grafting too quick. Your GP will just say to rest it for 6-8 weeks, if you can afford it go and see a sports/climbing physio
whatever you do, lay off the crimps for a few weeks!
