You could try using a heating pad on the affected area for a while. Then if it is still bothering you apply a Lidoderm patch or some Voltaren gel. Don't use ice, it's bad for RSD.

I've had over 50 IV's started in my left hand during the last several years, 2 of my veins are blown.... for the last year it has felt like my RSD is definitely spreading over to my left hand from my the right side every time I get an infusion. But within a week after my IV's the pain in my hand and wrist always settles down.

Everyone is different. But I wanted to let you know what I've been through and that I've made out OK so far...good luck to you....Sandy
