I have constant pain in both hands that are cold all the time. I have trouble holding utinsels, scissors ,and pens. My penmanship is a thing of the past. Most days I'm lucky to be able to sign my name.
When the pain breaks through the pain meds I use either Neuragen-$63.00 per 1/2 oz or Cobroxin-$20.00 per 2 oz. , these are topicals. I get these at Walgreens or CVS and both work great.
Also try Noxzema--I know it sounds crazy but it did work for me for a while. Just rub it in like hand cream.
I also sleep in a pair of micro-fleece gloves which really help keep my hands warm all night long.
Noxzema--just rub it in like hand cream. Cobroxin--$20.00 per 2 oz. Neuragen--$63.00 per 0.5oz Follow instructions on bottles.
These have all worked for me in combination with my oral pain meds. I have constant pain and numbness in both hands, wrists, elbows , feet, ankels, knees and neck. I hope one or more of these will work for you.
