Hello,
Is the pain he feels radiating,
tingling, numbing? Is your husband diabetic or have any signs of high blood pressure? What is his job profile? is he having job-related to more usage of wrist and finger?
If the RA factor has turned negative in the reports that it is a big relief that one of the differential diagnosis has turned out negative.
What is my provisional impression to the history is there can be two possible factors which need a thorough examination. One either this could be a
repetitive stress injury or two it could be
nerve entrapment.
But as I said this is just my provisional impression and without having a thorough examination of the job profile and more details about the history I cannot conclude it which can make you panic.
What I would suggest it please check this two things online or consult a doctor and see if either of one
fits into the category if not then we have to re-examine the history and restart the process of diagnosis.
On time being with related to treatment part, I would say try dipping hand in hot water and do wrist and finger movements. You can even use a sponge ball inside the hot water and perform squeezing activity. This should help to a good extent to control the pain symptoms until we come to a precise diagnosis.
Hope I have answered your query. Let me know if I can assist you further.
