Do your hands a favor and get Logitech's MX Ergo trackball mouse for $74

[Windows Central]

The Windows Central's review of this mouse. The reviewer calls it "the best mouse I've ever used." Trackball mice require less wrist and arm movement than a regular mouse, so they can relieve a lot of that strain you feel after using a mouse for a long period of time. The Ergo says it requires 20% less muscular strain to use. It has an adjustable hinge that lets you change the trackball angle up to 20 degrees for a more natural position.
