Neither is right. Actually the doctors found two possible solutions what might have caused the problems. First one, there is a kind of disease, when you eat too much red meat and game or drink too much alcohol, the level of some kind of acid in your blood rises and causes some kind of arthritis in your joints. Don´t know the name of this shit. So I suffered either that (because they found the high level of this kind of acid in my blood, that´s why they suggested I´d better stay away of the temptations) or it was caused by some kind of bacteria, which they also found. So I don´t know really.
