I'm extremely active and I play volleyball around 3 hours every day and I plan to play in
college. My hamstrings
are not tight, most doctors are amazed at my flexibility, and have suggested I'm hyperflexible.
I have tried a medrol dose pack, muscle relexers, a tens unit, a back brace, 7 months of physical therapy three times a week which included electrical stimulation, ultrasound, massage, joint mobes, strength excersizes, stretching, traction, and yoga moves.
