A few months ago, I really messed up my thumbs. I was digging trenches and sprained both thumbs. Stretches and exercises helped, but this hand massager really relieved the pain in my thumb: iReliev Hand Massager

Video is not sponsored it's just a look at a tool I personally purchased to relieve pain in my thumbs and it worked surprisingly well.

When I first saw a hand massager like this, my initial impression was that it looked like a gimmick. But after experiencing hand and thumb pain, I decided to give it a try and was surprised by the results! The compression massage was sufficiently intense, and I felt noticeable relief within just 15 minutes.

Personally, I use the iReliev hand massager to relax the muscles of my hand and wrist after working in the yard, gripping tools or using small equipment. If you experience pain in your wrists after working outside or typing all day, or if you have persistent arthritis in your hands or thumbs, I think you’ll love the iReliev hand massager! It’s a helpful tool that’s fun to use, easy to store, and effective at relieving sore hand muscles.
