I am having continuous muscle spams in back, neck and almost entire body. Always feel discomfort in neck and back area. So I have heavy head and strained eyes all the time specifically left side. Also I feel muscle pain throughout the body. I could sense whenever I stretch my body, there is a particular sound of muscle / firbes. If I do a physical activity, it starts paining e.g. My wrist, knees etc. This problem is there for more than 2 years. I feel tired all the time and I have gained weight. The physio I visited said that it can be fibromyalgia. Tests done: all the required blood tests, mri are done multiple times. All are normal. History: cervical straightening and lumber disk bulge.
