Weakness and cramping and Cisternogram

I have been suffering w leg cramps the last few days. It got so bad I couldn’t walk or use mt arms. My head pain and neck pain was sooo bad. Went to hospital and they gave me pain meds. The cramping happened before when I was on diomox. Does anyone else have potassium or movement problems. I couldn’t move at all and couldn’t even stand. It’s better but my left leg is still a problem. I can’t stand on it or lift it more than about 3-6 inches anyone have any of this?
Thursday got bad cramps and body went limp. Now sat night I still can’t walk unassisted. At ALL
I have a Cisternogram on Monday and Chiari surgery next Monday.
Anyone have a Cisternogram. It’s to look for csf leak.
