question: i have been having cramps at night for the past 3 years. i had blood work yesterday by my doctor to see if i needed potassium, magnesium etc. the report came out perfect except for a L 7.2 Mean Platelet Volume. the regular amount is 7.3-10.5. could this be the reason i am getting these cramps? They do not let me sleep. i have to get up at least 5 times every night. i do take 20mg furosemide everyday with 10 mg Klor Con Potassium. could it be the daily water pill also? i dont know what to do. the doctors dont know what is going on. do you have an idea?
