Yes, long standing and obesity may be the main risk factors for legs cramps so you should change your life habits first if you can. Second,leg cramps are a common and usually harmless condition where the muscles in your leg suddenly become tight and painful. It usually occurs in the calf muscles and in most cases there is no obvious cause of it If it happens sporadically then there is no need for any treatment or tests. But if this is common and affect your daily routine then some measures should be taken.
