Thanks for writing to us.
A fall on the outstretched hand with a persistent pain is likely to be due to a bone injury
of the wrist joint. You need to get an X-ray and MRI
of the wrist joint done to find out the exact cause. Avoid any movement around the wrist and use a wrist brace.
I hope this information has been both informative and helpful for you.
