In reply to Rhapsody: You're unlikely to be looking in the right place for a reliable answer. A good hand surgeon is who you need to see. Anything else is just messing about.
There's not even close to enough info in your description to have any idea what's wrong. For instance are you a teenager with a growth plate fracture, an older gentleman with some osteoarthritis or just suffering from the usual synovitis that most of us who abuse small holds suffer from when we suddenly decide to start climbing a bit more. Or the countless other possibilities, some of which are nasty.
Rest, a proper training progression and restoration of proper joint mechanics with the right stretches will sort out most synovitis. But deformed fingers sound a bit more serious than that. Do yourself a favour and sit down in front of a professional. If you are a teenage climber with permanent loss of function on the table if you ignore a growth plate injury, do it tomorrow, not next week.
Just as btw, the recent reviews have concluded that there is no evidence for any effects of Glucosamine use on joints (apart from placebo effect of course!). Likewise with contrast baths.
