I am a 52 old woman with Type II diabetes and for over a week my fingertips tingles and finges feel tight especially when I try to close my hands in a fist. The fingernails turn red when I close my hands in a fist. I also just recently moved and have lifted heavy objects, and I am not feeling any unusual strains; however just after I started laying laminate flooring (using a hammer almost daily) for over a week that is when I started noticing the tingling, swelling and tightness in my fingers. Also, I was off my Leventhroxine (thyroid meds) for about three weeks; and have been back on the meds for about ten days. Occasionally, my feet and ankles will swell; but my finger tips is constantly tingling with the tighness.
