ive finished my lengthening already at 5.5cm but ive talked to my neighbor and he also had burning nerve pain at 5cm. he finished at 8cm. so he kept at it. hes fine now walking unassisted. im still on a walker. the thing is the nerve tingling is still there after frame removal but nothing to worry about. i just wonder how other patients and doctor deal with burning sensation because every body is lengthening at 7cm tibias nowadays. feels like its a hidden secret or something..
