HELLO, IT MAY BE DUE TO ELECTROLYTE IMBALANCE. CONSUME WATER MELON, OR LEMON ORANGE KIWI IE CITRUS FRUITS OR VITAMIN C IE TABLET LIMCEE TO SUCK THREE TIMES A DAY. ONLY TYLENOL (PARACETAMOL)650, HALF TABLET CAN BE GIVEN IN FIRST TRIMESTER OF PREGNANCY. LEG ENDS SHOULD BE UP DURING SLEEP IS ALSO HELPFUL. I HOPE THIS IS SETTLE YOUR PROBLEM. O.K, BYE.
