For 18 months my quad has been going through a vicious cycle of healing and getting hurt. I know I tried to push it hard too soon and have put myself in this predicament. It is frustrating not being able to squat above 135. I think it may be scar tissue that keeps breaking/tearing. I've been advised to get rid of the scar tissue via massage. The injury is accessible, so I've been gently massaging it myself lately along with a TENs unit and a thermo wrap. Any other ideas to accelerate the process? Or must I just bide my time patiently?
