If you have what feels like a high hamstring pain right at the bottom of the buttcheek, I can fix this. It took me years to discover the source, and when I did, I learned how to heal it. Apparently it is a common running and biking injury but even some local chiropracters and physical therapists have not accurately diagnosed it. I have helped heal several with this as well as the related sciatica. Contact me, Duane, at maurybike@gmail.com and I will be glad to help you.
