Hi. I'm not sure as I have never been pain free since this happened but some days are better and then I feel the next day I got hit by a bus. The neuro told me that sometimes you may hit a rock bottom and then start on an upswing. Also that there are going to be days where things seem to be doing better and then a real bad day. She didn't give me an exact why. It may be if you were doing more though some days for me its even if I barely move. I try to put it in a perspective though hard when that hopeless pain comes back but even non pain suffers have days where they feel like crap. I'm glad your seeing better days that is a huge positive and hope it continues. Also maybe someone here as I know little could tell you if you may need to change something with the b or something else if you state more.
