I bought my mat in mid October, it’s now the end of November. I wish I could say it’s entirely alleviated my hip and foot discomfort, but it has made my hip pain less noticeable in the morning when I get up. I use it during the day, all day, off and on, and am thinking of putting it on my bed to use thru the night. The mat itself is very nice. I keep a thin blanket, folded, on top of it to hold in the heat, and it is very comfortable. I’ll report back in a while to see if my hip and foot pain are responding. But so far, there’s been a small improvement. I have had this hip pain for many years, been to many docs about it, many x-rays, MRIs, etc and they’ve found nothing other than arthritis. So, going forward, we’ll see if this mat can help me more. Thank you for making it.
