In the past couple of months I've been getting an occasional sharp pain in my thumbs, first the left only then both, when I put them under strain (turning taps or wringing things out, for instance). I also have lost some feeling in them. Saw the doctor today and he reassured me that it probably wasn't diabetic nerve damage but the early stages of arthritis. It hasn't developed into carpal tunnel and he suggested trying glucosamine (but to be careful about the dosage as it could affect my blood sugar - oh joy) or cod liver oil.
I'm also disappointed with my weight; I'm back up to the same weight I was at this time last year, 90 kilos (199lb: 14 stone 3). I'm going to have to take more exercise (I've not been walking as much as I was, for a variety of reasons) and watch what I eat.
