Both Donna and I have experienced nocturnal leg cramps or spasms. Back of the leg. Very painful. Does it ever happen to you?
In order to treat leg cramps, it is advantageous to know the cause of such cramps. From my research, I gather that dehydration, low potassium, low sodium, low calcium and underlying muscle injury can contribute to leg cramps. When I have experienced leg cramps, I rub the area vigorously, apply ice, drink a V-8 juice (high in sodium and potassium) and have a few glasses of water. Know what? The cramp goes away.*
The last time this happened I had played golf all day without stops. Walking. No water. Had a bit of lunch and a little ice tea and no other hydration. Then we went out in the evening. A wee bit of red wine. No water. Come nighttime, there was little inspiration to guzzle a few glasses of water or V-8 at bedtime. Then at midnight – KA-BOOM! Leg cramp. My RX worked perfectly.
