Is jellibend actually helpful?

Is this actually helpful?

I'm hypermobile and have significant hip/low back issues (feels muscular and skeletal pain) and also traps/neck/jaw,shoulder muscular pain. Does jellybend actually help?

Which ones do people use to help with these two problems? Also does it get too hot in the summer?

Also I found when I wear tight compressive pants or tighter pants with no stretch that the way I am compressed on my hips makes my hip muscles on the injured side have to work extra hard to keep it in my socket right. (I have hip cartilage damage on one side plus hypermobility). Any recommendations?
