My spread actualy started without much pain initialy it was the other symptoms that seemed to creap in, cramping and muscle twitching.. then came the sunburn feeling then the deep ache and the surface burn, I also got alot of stabbing pain very early on..

What other symptoms do you have?
Do your hands sweat alot?

I would up your antioxadents.. grape seed extract, rooibos tea, green tea, dark vegtables..
Vitimin C (containing antioxadents) has been shown to prohibit CRPS from happening after a wrist break in a couple large scale studies done.

And use the new areas as much as you can without hurting yourself too much.. try to stay limber, slow stretches, mabie a foam ball.. use the area as you would normaly as much as possible and touch the new areas as much as you can to stop the sensitivity.. nothing to the point that you feel may be hindering.. trust your instincts and start self treatment now.
Elevate those hands too, and soak in epsome salts baths.. 1 cup of salt to a tub to start.. There is Magnesium in the Epsome Salts that helps inflamation and helps relieve pain as well.

Lol.. bossy arent I only cause I care, and I think it'll help the spread if it is and your pain even if it isnt spreading.
