lump in palm sounds like dupuytrens - have a search on here for extensive thread (dead prevalent amongst climbers)
Friction massage doesn't reveal a point which I yelp, nor does it convince me that this isn't the start of something worse.[/quotelHmm. The yelp is normally a good indicator. Guess some massage wouldn't do any harm?
I think it is very difficult to tell whether discomfort is scar tissue breakdown or actual injury, primarily because the processes are the same, i.e. tearing of fibres, both of which leads to swelling and inflammation.It seems unlikely, if you didn't feel it come on, that you have anything worse than a very minor sprain, which should sort itself out fairly quickly.Again, in terms of management, whether it is a sprain or scar tissue breakdown, it makes little difference. Either way, you need to let the pain subside before climbing on it again, and you really ought to avoid anything that is acutely painful.
