Sweden...people on here have told you several times...and you keep ignoring what we have to say.
I'm going to make this very direct...GET ANOTHER SURGERY! X-LEGS is caused by misalignment. Even if you were Goliath or the strongest, most fittest person in the world...IT WILL NOT FIX YOUR X-LEGS! You need another surgery. if you reply with "I don't have time" or "I can't be bothered" or "I don't have money" then you have a problem. YOU NEED TO GET SURGERY TO FIX IT!
As far as stretching too far...I met two Australians in my country who both grew 6 centimetres and they don't have nearly the problems you talk about. They both say they are fit and can run, jump, and walk just fine. They both claim they are back to 99% to the way they were before the surgery. There is no reason for them to lie about that.
Heck ,even Medium Level Drink Of Water grew to 7.5 centimetres and the only problem he has is kneeling on a hard surface. So, again, nowhere near as the problems you are having.
I hope I have made my point very clear to you. GET SURGERY TO GET THE X-LEGS FIXED! I really hope you get the message this time. If you don't, then I give up! Best of luck.
