My daughter was involved in a car accident in Jan 05, she was 15 years old at the time, she had her L4, L5 fused, and was told she would be fine after she healed. However she has been experiencing back pain, and her legs will not go straight out when in a sitting position, the doctor says that her hamstrings are tight, and she needs to stretch them out. She has been doing stretch exercises for 2 years now with no sign of improvements, the pain is getting worse and she is getting cortisone shots in her back every 3 weeks, until she is scheduled for surgery to have the rods removed. Now she is starting to experience pain after the injections, she is 18 years old and misses so much school due to pain, does anyone have any suggestions
