So I've had the same scale for a few years and it has served me well all this time. It was never anything fancy... I think it's a Weight Watchers digital scale. I bought it at WalMart for like $30.
When I weigh myself, I always check twice, just to make sure the number is right. It's like seeing it a second time will cement the number into my brain, I guess. Well for like a month, whenever I weigh myself, the number is different each time I step on the scale. I've stepped on and off like 20 times thinking I was crazy, but every single time I stepped on the number would read differently.
I'm nursing a 2 week old knee injury, and I had been thinking that I was standing on it differently because of my knee... and that might be affecting the number. Except that my knee is basically doing fine now (still brace it when I exercise, but back to normal walking otherwise), and I don't think I'm standing on the scale funny... but the numbers continue to jump every single time.
Anyone with experience on what this might be? Is my scale just dying a slow, painful death? Should I maybe try changing the battery? Do you think I need a new scale? Or am I really just suddenly stepping on it so differently that the numbers read different every time...?
