Hi.
First of all, there could be many causes for aches and pains in joints etc. Muscular problems, skeletal problems, nerve problems, high Bg levels (general aches and pains), also drug related. Which brings me to one of your previous posts.......
You are we believe taking Citalopram.....this drug has some very odd side effects which can include symptoms such as you describe.
You should discuss this with your GP. It MAY be Diabetes related.......then again it may not ?
