Took about 3 months. Mine was 2 disc bulges pinched a nerve that ran down my leg. At first The whole front of my left thigh felt like a big steam burn. The area got smaller slowly and by 3 months it was just a thin line, about a finger width from the top front of my thigh to knee that is just numb to this day.

The pain in my spine was roughly along the same time line.

The treatment I had was just over the counter pain medicine and then physical therapy to strengthen muscles around the area, apparently more muscle makes it less likely to compress and pinch a nerve again.

That was my exact thought, and the only thing I had to say about it.
