I been a Diabetic so long unfortunately I do not use alcohol on my fingers or injection sites. I asked one of my local pharmachists about the problem I'm having on all my fingers on my left hand. I asked him if I should start testing my blood sugar on my arms like I see in some commercials. He said blood readings are not as accurate testing on the arm as it is on the fingers. He told me to discuss this w/ my M.D. (Endocrin.). Looks like next weeks I tell my M.D. about this major problem I currently having.
I found rubbing alcohol causes the skin to harden. I wash my hands with soap and water and dry with clean towel. Look into new meters which allow blood from forearm or stomach.
That's all I have been using for testing blood. Meaning lancets. Maybe I should look for some lancets that have a thicker needle. Can't poke my fingers on the right hand because that's the hand I use for writing. Had my Mom poke my fingers on the right hand and could not wright due to the pain/sensitivity.
Use lancets for pricking fingers for blood test. And you can certainly use your right hand fingers for blood testing. Its not a big inconvenience and won't affect your work!!
