Hand Cramp

I've been jumping for over twenty years and in the last few years I have started to get cramps in my hand after a few jumps.  I only did one yesterday and still had hand cramps on the drive back from the DZ.  Has anyone else had this happen and any suggestions as to how to stop it welcome.  I wear gloves, even in the summer.

My first guess would be dehydration.

Remember to sip plenty of water throughout the day.

First signs of arthritis !
