I have been feeling especially in the foot. Is this normal? The bones in the foot seem to bunch up, especially the toes minus the big one.
A common cause of overnight cramp is
dehydration. We tend to underestimate the fluid lost through perspiration, especially in warm weather, so make sure you have plenty to drink during the day. You can't beat water out of the tap, but almost any sugar-free beverage will help. Unfortunately, alcohol tends to exacerbate the problem.
Diabetics are known to be more susceptible to cramps than the general population. It can occur with type 1 and type 2 diabetes, but appears to be more prevalent with type 2, possibly because patients with insulin resistance tend to lose magnesium in their urine, contributing to lower levels. Some forum users find a magnesium supplement helps.
Should you be unfortunate enough to experience another bout of cramps in your legs, whatever you do, don't point your feet! It's a natural reaction, but prolongs the agony. Instead grab your toes and pull upwards towards your knees. You may want to support your feet in bed with a pillow. I find that simple precaution prevents me from flexing my feet in my sleep.
