Hello. I'm a 24 year old person. My problem is that most of the time I feel uneasiness in my lower back. It becomes highly uncomfortable and the easiness is in the sense that any movement becomes painful and it feels like there is any friction going within the bones. Also sometimes my ankle pains when I wake up after sleeping or go for running etc and that's y I am unable to go for run. What is the problem and can I go for exercise and join gym and go for crunches etc. I'm also overweight.
