Re: synovial cyst - thoracic area
Sorry no one answered your post. Have you had the nerve block by now?
I suppose if the cyst is pressing on a nerve, the steroid may temporarily shrink the tissue enough to provide a bit of relief. But with a fluid-filled cyst, I think it would be a temporary solution.
I believe I read on another of your posts that you have had arachnoid cysts previously??
