I don't l know, but I am at a loss to understand why I feel so consistently rubbish and in pain so am seeing doc on Tuesday. My limbs are painful, and worse at night, and I feel as if everything I do is a massive effort, feeling tired and out of breath. It has all been much worse since I had flu and covid jabs (no obvious reaction/temperature) and also a denosumab injection (for osteoporosis) in quick succession. So I do not now what is going on - but it is all a blessed nuisance.
I am already in pain with failed hip replacement and previous back surgery, so this is the last thing I need.
