Paul - Colorado 2018
"I did a little experiment. On Sundays I play soccer on a hard turf field. It is a synthetic surface. After these sessions my back will hurt that night in my sleep as well as the next night. I intentionally have been doing this for several weeks to gauge my pain after these sessions without wearing the MerryBack®.
Last Sunday, after playing, I wore the MerryBack® for an hour or so and the following day for about 3-4 hours. I had no pain whatsoever in my sleep nor during the day while wearing the MB. I also have no pain today."
