It didn't help ME with chronic pain, but it does help my wife with her fibromyalgia.
I'd wager if you are up in weight, and chronic pain is in any of your weight supporting areas (hips, knees, ankles, lower back, etc) then chances are your pain could be weight related.
My parents are 100% weight related issues, and when I was trying to lose weight in 2013-2015 I tried to get them to do light stuff with me. Walk around the trees behind the house a few times. A couple light calisthenics. Ride some shitty cheap bikes around the park.
Since then their knees, hips, and ankles are their biggest complaints.
"But that still doesn't mean you'll get to play it"
Well then it doesn't exist.
And until I actually am staring at the introduction screens, it's vaporware.
Have we gone on long enough to see the endless wheel of "HALF LIFE 3?????" once again spin back around? I remember seeing a handful of these a year, every time valve did anything.
Expect nothing, and you can't be disappointed.
