I've had this..mine don't last 30minutes tho.

I get "pains" where I have had arthritis issues. Right Knee,
right thigh (MP), left ankle, sometimes my neck.

Your hand may be a stress thing from using the crutches.

Also reducing the Mirapex may be giving you a withdrawal syndrome. Drugs that affect neurotransmitters (Mirapex affects dopamine), tend to do that for weeks/months after decreasing or discontinuing.

You could try Salonpas patches on your hand. I find they work well for me for my hot painful spots. Get the ones with methyl salicylate in them (they make other kinds), for best results.
They are inexpensive--the small ones. You can cut them for fingers/toes.

On that website is their new stronger patch, but I haven't found it yet in stores. This newer one looks really nice to me..but is much more expensive too. This new one is FDA approved...a big thing these days for OTC products.
