(Question) Severe hand numbness! Will stretching help?

I am currently experiencing severe numbness in my right wrist and fingertips. In particular, there is a tingling sensation that feels like radiating pain extending from my thumb to my index and middle fingers. The symptoms have been present for about two days, and I am wondering if I need to go to the hospital immediately, or if I can treat it myself by starting with stretching. I used to experience occasional pain from overusing my wrist, but it would usually improve quickly after a massage. Now, however, the tingling sensation is severe even while I am sleeping. Until now, I have only experienced pain; this is the first time I have experienced this tingling sensation.
