If you have had knee surgery or suffer with back pain like myself, after physio sessions you need to be supervised with your rehabilitation to make sure your heading in the direction (prevent any further injury)and look towards a speedy recovery. It's your choice where you go! running in the park after surgery maybe difficult....... It's your health! and you should look after it. Es Physical Health seem to be getting a hard time on here, just for expanding their business which has been running a number of years. I wish Es Physical Health all the best and keep up the good work! (tu)
