The first question here is what do you mean by 'Issues'? Pain? Cramps? Squirting blood? A general inability to keep the weight steady?
If the later is the case, yes, there are plenty of wrist exercises one can do, basic dumbbell wrist curls/extensions might help you, and they don't require any more equipment than what we know you have on hand. Just hold the DB's at your sides and 'curl' the weight in moving just your wrist. Then pull it the other way, i.e. pulling with the top part of your forearm.
If you're having pain or soreness, that's something you might want to be more careful of. Try resting that area for a few days. Or start using a 'natural' keyboard. Don't forget to stretch your wrists before a workout, and you could always try using Glucosamine/Chondroitin Sulfate supplements,
I've been using them for a while now, and they seem to help (the documented scientific evidence is rather lacking, however they don't seem to do any harm, (yet))
