Welcome to the forum. Swelling on the same ankle ( R) again after a fall should not be neglected. You should get an X-Ray done to rule out any fracture
or hair crack at the ankle. You should consult an orthopedic surgeon.
Since you have history of fall and bruise
on the same ankle 2-3 times, the numbness
that you are experiencing may be due to peripheral neuropathy
. It can be due to peripheral nerve
compression or bruise. It can result from peripheral nerve trauma. Hot fomentation can give relief. Pain relief spray may be helpful, take calcium tablets. Get clinically assesses for better diagnosis and treatment.
If you have a fracture get it crepe bandaged or plastered as may be the prescription of your treating doctor. Have a nice day, take care.
