The older your therapist or trainer, the more likely they are to muddle up what to call your tendon pain. The younger your trainer or therapist, the more likely they are to waste your time with an obnoxious mini-lecture if you use the wrong word.
There are hundreds and thousands of therapists and trainers, that, when confronted with your hurting hamstring or your terrorised tendon will simply dive in and rub that bit! Maybe they will give you a specific stretch and maybe a reassuring “There there, therapist kiss it better”
The reality is that your body is a global system and highly interrelated. Leg issues can be caused by core issues, how you chew your food can screw your knee!
