Hi and welcome to Healthcaremagic. Thank you for your query. I am Dr. Rommstein, I understand your concerns and I will try to help you as much as I can. 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. In some cases there may be predisposing conditions such can be seen in pregnancy, after exercise and certain types of medication, such as statins or in liver disease. The best way to manage this is to stretch your muscles regularly. In some cases magnesium or calcium supplements may help Have enough fluids and avoid long sitting, regulate body mass. In cases of progression or if there wont be improvement, you need to see doctor, to rule out some neuropathies or vascular disrders which are much les common but should be considered if there wont be improvement on these measures that I have mentioned.
