Carpal Tunnel Syndrome has wrecked many a career. Luckily you seem to have noticed it before it got too bad, that's a good thing. Also, it might just be tendinitus. I had it awhile back, because I was playing too much guitar coupled with lifting weights. My pysiotherapist said, "no more weight lifting", and that was that.

Do yourself a huge favour and wait until it gets better. I suggest seeing a professional. You may find that simply waiting a week then playing maybe half an hour a day for a bit will fix it right up, or maybe you won't have to wait at all. Depends... just don't make it worse!
