Hello, I have big problems with all muscles in the body. they hurt and burn, especially when I sit on hard chairs it is very painful. it is also painful for the back to lean on a hard backrest . I also suffer from more and more getting looser tissue. There are some places where the tissue is swollen: near the ankle, on stomach. it feels as strained and injured muscles and injured tissue. Has anyone similar problems and what can one do about it? (movement or training makes it worse.) Is muscle pain a result of diminishing muscles and tissue?
