<s>[INST] I have had Back pain for 30+ years. I have had tests, 3 back braces, a shoe lift, PT several times. The more I try to do the worse I am. I had a nerve block done (Hoping it might help. The first one was extreamly painful. 2 weeks I went back and he did something to my right let. It felt like I was been hit by lightening!! They said it was ok ant it would go away after a week ago. And treated me with meds. But continually badger me about doing another. My right leg feels like someone is taking a HOT poker and jamming it up and down my right leg. This is still going on 3 years later!!! My back,,, 3back braces, shoe lift, PT once recently, acupuncture and I m STILL in pain. I m soooo over being in pain I could cry! [/INST] Dear friend I am sorry to know you are in such a bad shape.I will suggest you not to go for another nerve block .Your pain just may worsen.You should continuecwith your brace and PT.A  regular home regimen of physiotherapy can surely alleviate your most of the problems.You know ,back problem is very common and nagging problem.So instead of thinking about radical surgical approach like nrrve block operation you should settle for conservative way like physiotherapy.also go for some lifestyle changes like avoiding lifting heavyweight,bending forward too much.Hope,in this way you can get rid of this back pain.my best wishes for you. </s>
