Hi Jon, I've been a chronic pain suffer for 6 years years now and I sympathise with you, it;s a horrible way to be. I have had numerous injections over the years to give me some relief and have had great results in the past. Your legs have obviously been through an awefull trama and shin splints take time to heal. It may be worth talking to your doctor about. I sincerely hope all goes well for you. Best of luck Leanne
