Thanks for your question.
Slight numbness on the right pinky finger can be from the nerve compression at the wrist more like carpal tunnel syndrome.
Vitamin B12 deficiency, hypothyroidism, diabetes should be ruled out.
these conditions can be checked by the simple blood tests.
Usually repetitive use of your hand can cause this probem.
get checked for b12 level
and try to avoid long time typing, lifting heavy things
you can wait till that time.
yes that is the likely problem.
Try to rest your hand in neutral position at night.
You can use a CTS splint ( wrist splint)
yes that is the likely cause not median nerve
no that will also help.
wrist is the likely problem since you do not have any other symptoms.
usually within a week
yes that will also be good
500 to 1000 mcg daily
