Hi Paul, I'm going the same neither better nor worse. About the back pain, It's about 2 years that I'm suffering of lower back pain when I standed for a long time, I have never worried about this becouse I thought it was something related to my scoliosis......now I'm wondering if this pain was the first symptoms of these neuromuscolar issues I'm going through. What about neck pain? in the last days I'm having also neck pain and stifness. I feel like I'm 80 not 33, I'm tired of this situation...I'm trying to do my best to walk as long as i can and to stay active but it's not easy. do you have ever experienced joints cracking and popping? I have developed joints cracking in knees, ankles, neck, shoulders.
