I started having problems with my 5b cascade around 3 months ago, while I was preparing my graduation from ESAC juggling act.
Suddenly, after more that 10 years of juggling, I wasn't able to comfortably do more than 200 catches. Then it went down to 100, then to 50 and soon I found myself unable to juggle 3 balls without feeling some real weirdness in my right hand. It quite literally felt like my right hand had forgot how to catch and throw!
The thing is, at first, I didn't suspect it could be an injury as there was no pain involved. Having got mildly injured before (while juggling, running or doing hand to hand) I though I knew how injuries for overtraining came: you train a lot, you feel pain, you train more, you're injured! (and even when you arrive to this point, what doesn't let you continue is pain, not loss of coordination).
I decided, therefore, that maybe I had been lazy: maybe I wasn't training enough. So I trained more. So it got worse.
More tension in the catching and throwing, more fatigue, more frustration.
2 weeks before the presentations I finally stopped training and, when the presentations finally arrived, I just dealt with them profiting from the adrenaline that comes naturally when you do any performance you really care about. Performances went well, I was happy. My hand was still shitty, though.
Almost a juggleless month has passed since then and I've already visited 3 different physiotherapist. Their diagnoses have been kind of different and, funny thing, each one of them has told me a different way to use ice (I didn't knew there were so many options!)
Main thing to rescue from all their talking, however, is that things like this happen when you're throwing and catching (and, more generally, doing a very specific movement) all day long. The tendons may get too tired or the muscles may get in the way of a nerve or a bone may move a little bit and it won't always feel like you would expect it to feel (deeply painful, for example).
Sometimes it will feel just weird as hell.
Don't panic, don't forget to rest and stretch and don't fear that the physiotherapist will tell you "and what am I supposed to do!?" when you explain him that your backcrosses don't feel the way they used to.
I wish somebody had told me about this things before.
Have you ever got injured for juggling?
Had an injury, doing other activity, that seriously threatened your juggling?
How did it arrived?
How did you dealt with it?
How well did you recover?
What advice would you give?
