Wired or Wireless Mouse?

I've been using my computer mouse for 3 years. It's been quite a long time. Actually I don't know if what's the life span of this gadget. Do you know? I'm just complaining about my mouse because it's hurting my hand every time I'm using it. I don't actually know if what's going on with it. My recent one is a wired type but I'm thinking of replacing it with a new wireless mouse. Do you think my decision of getting a wireless type is a good choice? I'm just asking anyone's opinion. So which one Wired or Wireless Mouse?

Wired
