Hi, I am the father of a wonderful 4 year old. He has a diference of 6cm .he is due to go for his first surgery next tuesday. we pray everything goes well. Till about 4 months ago we attended regular physio .it was not really doing a lot for our son, so we went to our local herbalist . they gave our son a course of herbs and started a course of muscular repatterning. these people are the best thing that has happened in a long time .Our son has a lot more energy and never complains about pains any more .It has worked wonders on the muscles on his leg and removed the bunching in the muscles, he has developed wonderful range of motion. The hospital are not too keen but dont discourage it . we intend keeping this practise up through out the process. we hope it will get our little man back on his foot sooner rather than later. I just thought this may help anyone with an op in the future. yours a nervous Alan in Ireland
