I started the trail shots almost two years ago. I did my first RFA 1 month after the trail. It lasted 4 months. Then I did my second RFA and it lasted 7 months. I just did my third this Dec. and so far it's been great!!! My pain level was up to 8 and 9 before I started this journey and now my pain level is down to a 2 and 3. I broke my back in 2 places in 1996, and this PM doctor is the first one to offer me this amazing treatment. Not sure where you all are , but I'm in NB Canada, and I would tell anyone with nerve damage or lower back pain to start the trail asap.
Desperatewife, yes it works, my pain level used to be 8 to 9, since doing the RFA and the PFRA my pain level is down to 2 or 3. Also losing weight helped me.
