I have had episodes when my skin goes very hard and chunky. It especially affects my right arm going across my back. The skin feels wooden to touch. The first skin biopsy was negative from my arm. However the recent one from my back has been reported as scleroderma. It responds well to steroids.
My rheumatologist is reluctant to agree with the biopsy results as they don't know the reporting pathologist.
I would be grateful for any thoughts, as I do feel slightly confused.
