I had awful sciatica about 12 years ago that was a result of a herniated disc from a bad deadlift - MRI confirmed this. I too was wearing a duty belt at the time and had to sit most of shift. It was ****ing horrible. I had to eat all my meals and watch TV laying on my stomach with a pillow under my chest to keep a constant arch in my lower back. I saw a chiro who used current right on the injury itself. He'd turn the machine up all the way and I would be in tears. 15 minutes three times a week for three months. He also did some adjustments but the other big thing he go me to do was stretch for a half an hour every day. Intense stretching. A year later I had another MRI and the same physician could see ZERO evidence of a disc herniation. It completely healed . Within a few months I was squatting and deadlifting more than I ever had previously. Now and then I will get a little tingle in my foot if i sit for a few hours in a row at work without walking or moving around but I can stretch and 'pop' the tight area. I also must keep working my abs at least three times a week or I get some lingering pain. Anyhow, that worked for me. No painkillers or anti inflammatories EVER. IMO although they will reduce swelling they also mask the injury. Just my two cents. 30 lb duty belt ? Cop ? Firefighter ? Please say firefighter.
