I got tibia stress fracture and operated 3 months before but still bones are not healed there is gap in two bones but I don't have pain, swelling I can walk with elbow cluthes but few Dr is suggesting me to not walk and suggesting to make one more bone grafting surgery if not done plates will break.. Some Dr is suggesting to wear PTB casting this will help for walking I am very nervous and afraid Pls some one suggest me correctly..
