Hi. I strained a hamstring sprinting last year (full on seizing/locking up - beyond painful!) and despite taking great care rehabbing & not pushing too hard the past 9 months I still feel weak & tight in the posterior right leg chain (Achilles up thru hamstring). Comes and goes a bit, though - which is a telltale TMS sign, I know. But...this damn “injury” is rooted in a definitie traumatic event, so...I waffle Any other serious athletes out there have success stories about similar cases to share?
