+1. Prevention is better than cure.
This is the first stop, be proactive rather than reactive in such matters.
Pain is not the issue as pain is an emotion, and as such is tied in to the pyscologicol way we view it, if we think its going to hurt then more than likely it will as out brain accomodates our thoughts, as will telling ourselves it does not....justification for pain helps endure it.
My pain is not your pain, so how it is quantified is a personal thing, pain has its use, but it also has its draw backs.
Shaking out the hands, as mentiond, is not so much relieving pain as relieveing muscular tension via increasing blood flow to and through muscles. This shaking also vibrates the muscle, so vibrates the nerve and nerve sheaths, so it helps relive the sensation of pain that we could associate with such tension.
Stretches do the same thing, the help relieve muscle tension by stretching the muscles, as well as stritching the main nerve branches.
Many people do not associate that as muscles contract and elongate, then so must the nerves that service them.
The nerves run inside protective sheaths so they do not tear. If this movment is inhibited then we say they nerve is 'trapped'.
The neve is being held and stretched rather than moving freely within the sheath, so we feel the effects more because the pain is not assosiate with a nerve ending response of a singe area, but along the length of the nerve as it is being over stretched due to the addition of a 'new fixed point'....which is what an entrapment is.
I teach that is you shake out your hands you help shake out problems. Learn to use them before and after playing, or as flea does inbetween songs if needed. Use them with stretches and warm up and help keep your hands healthy....or at least give them a better chance to remain so.
