Mere,
Yes, I experience a lot of pain and stiffness, puffiness in my hands, feet too. You mention your sed rate being elevated, I am not very familiar with this, but if memory serves, when my doctor has tested my sed rate it seems as though he told me if it was elevated that it may be caused by rheumatoid arthritis. I could be having a senior moment

and just thinking that was what he said, but has your doctor mentioned that?
