thank you for posting your query in healthcaremagic.com..... see there are many causes of muscle cramps like excess use of a muscle, dehydration, electrolyte imbalance, atherosclerosis and even nerve compression... you are saying that you are having this problem from long time....people with diabetes or thyroid problems experience cramps more than normal people....so do you have any co-morbidities like diabetes hypertension thyroid problems etc? the treatment should be like- take plenty of fluids and fresh fruits... do a complete blood count, serum sodium potassium calcium magnesium... do a ppbs, t3, t4, tsh... take some muscle relaxants to reduce pain.... get back to me with the reports.... hope that was helpful... regards
