I am having weakness throughout the body. All bones, joints are causing pain. If somebody who is strong presses any bone it is causing pain. Sounds are coming when I use any joints like neck, throat, knees, hip, elbow. If I use some joint for some time it is paining. My muscle strength is very poor, muscle is very less. I am trying to build muscles. My vitamin D is normal. To mention, physical activity from my childhood is very less and also I am overweight. What this could be? Thanks in advance.
