First time posting on this site. My right wrist is a mess from an old injury; if I dont watch it I can easily get ganglian cysts. At the tattoo shop I use an old Kung Fu training liniment called Te Teh Jiao or Dit Da Jow. It is used in Acupuncture for painful joints, bruises etc.; mostly from repetitive type injuries from martial arts training. Works pretty good if you put heat on it after lettin it absorb into the skin; you can usually pick it up at a Chinese Kung Fu school or there are some sources on the web. We make it ourselves and use it quite liberally; smells abit funny but is alot better than sore wrists. I also use a form of stretching known as nerve gliding; simple flexion exercises for the forearm commonly practiced as a warm up for Aikido. It helps to stimulate the nerves in the arm.
