Hard to say: There are many potential causes and you should probably be checked. One of the more common causes of numbness in the hand and fingers is known as carpal tunnel syndrome in which the median nerve is compressed at the wrist. Thank you for your question.

Ganglion?: Need more info to help sort out why your hand and arm might be going numb. Numbness is caused by a decrease in blood flow to an area, such as when your leg goes to sleep when you sit on it, or it could be a pinched nerve in your neck, rare at your age, or in your arm. A lump the showed yp quickly could be a ganglion, which is a fluid filled cyst. If it is bothersome, get it checked out.
