I also experience muscle stiffness
and cramping in my right calf
and, as of today, also in my left
leg and calf. I have been told by my primary care doctor and my neurologist that I have benign fasciculations and not ALS based on bloodwork, physical exams and symptoms. However, I am still concerned because the cramps seem to be getting worse. I even have cramps/fatigue in my upper right arm now, especially in the morning. I am concerned about fibromyalgia now.
