I Had Severe Leg Cramps On Upper Right Leg And

I had severe leg cramps on upper right leg and in calf muscles at 3:30 a.m. then again at 12 noon. Massaged upper one about 30 mins. some relief but I can feel it is going to start if I bend my leg the wrong way. Have had 6 cups bottled water, olives and some brine for the sodium, one pack of Emergen C for the Vit C, try to
stretch it out but I can still feel some mild "cramping" Pain so bad I almost passed out. What more can I do? Had some discomfor t in left calf also. Cannot find a comfortable position for my leg.
