I just heard from someone that "most" T1D people suffer from loss of finger sensitivity over time. She said that Joslin is very concerned about this issue at the moment, but she couldn't direct me to any research. I've asked my doctor about this, and she was not concerned. I have tried to find information about this on the web and have not been successful. Does anyone know anything about this issue of loss of fintertip sensitivity due to blood sugar testing? Any websites with research about this? Should we be pushing alternate site testing, or am I making unnecessary trouble? This is a huge issue for us since my dd wants to go into music professionally. Her fingertips are rather important to her!
