Only just spotted this last post. I agree. It's just insane and the so-called logic escapes me completely. I have been having cortisone injections in my basal thumb joints for about 7 years, but the CCG decided to discontinue this service last September. Because of the cortisone, my hands are currently very much less painful so I can currently do quite a lot, in the way of chopping vegetables, pruning in the garden with my super secateurs or loppers etc. It's the small complex movements that cause me difficulty. I can just about sew on a button, but that is a real struggle and only to be tackled in an emergency. I would love to embroider again, but I'm afraid that's past hoping for. The lightness of disposable syringes, plus the fact I only ever need to take an absolute maximum of five units, means I can inject without a problem.
You are plainly in a difficult postion. I wouldn't want to have to depend on a visting nurse either. My aunt needed one after a cataract operation and they were never ever on time. I too have had to draw up insulin from a pen cartridge when the DSN prescribed them by mistake, which was unbelievably fiddly. I wonder how many other people have this arthritis/injecting problem ? I just hope some other answer materialises for you.
