My wrist keeps feeling numb… Is it just fatigue or a sign?

Lately, I've been getting a constant tingling sensation in my wrist, which has been bothering me quite a bit. Even if I use my smartphone for a long time or do just a little housework, it starts to ache quickly, and I feel like I have trouble lifting things. At first, I didn't think much of it, but as it's gotten more and more uncomfortable, I'm worried that I've strained my wrist. It doesn't seem to get better even with rest, so I'm constantly debating whether I should go to the hospital or wear a brace.
