Have you noticed a reading that is different based on the finger you use?

I am type 2, and have been for a while, but I am just noticing either my meter is broken, the strips are bad (expire in november), or my readings are different based on the finger I choose to prick.

Today, I wanted to test a few things around readings. Washing my hands with different soaps, using paper towels vs using a clean towel to dry my hands off, and I am testing a new energy bar called Quest (I'm sure you guys have already heard of it, but I'm testing to see how it effects me).

I tested using my middle finger and got X. 10 mins later, I tested using the same hand, but ring finger and got x + 27. Tested yet again on the index finger of the same hand 5 minutes later, and got X - 7. A 34 point swing in a matter of 15 mins and with nothing to eat or drink seems really strange to me.

I will keep testing, but I wanted to see if any of you guys have had similar experiences? I will be bringing it up with my dr when I meet with her next month.
