breaking scar tissue?

hey all, I have had a bad hamstring for awhile now, its mainly due to my back, which I have put a lot of work into. I think I might be alright from now on as I’ve had a fair bit of physio, but I’m fairly sure I have scar tissue which is keeping the injury from healing completely. Unfortunately I don’t have access to EMS machines or any fancy equipment really. Would the best way to break the scar tissue down just be to massage it after a heat or ice sesssion?

I believe the best way to break up scar tissue is to get ART or cross-friction massage done by a professional. Post your location and someone may be able to recommend someone.

x-friction but by a good therapist!
