His hands hurt so bad😭his fingers look like little sausages

A little more information might help. Is this you, or somebody else you are asking about? The best recommendations will come from a rheumatologist, if this care is currently being provided, and whatever treatments are ongoing. If treatments aren’t working, then another consult would be in order. NSAIDs, and resting the hands would, at this point, be about the best I could recommend.
