I also have Fibro and I have to stop occasionally and stretch my fingers. Also, if I use my right hand too much, I'll have muscle spasms up into my shoulder...then I have to quit sewing (or being on computer) for a while. I get the tingly feeling in the tips of my fingers, also. I use the Handeze gloves and they help a lot. I don't know of any magic cure for the pain...have tried most every medication there is. Just stop and rest and stretch.
