This is Dr. David
I am sorry she is having these episodes.
she could be having pinched nerves in her spine from spinal stenosis or a herniated disk
or these could be due to muscle cramps from low potassium or low magnesium levels in the body.
seizure activity or TIA would be less likely.
she should get blood work to check her magnesium and potassium levels.
he might benefit from a spine MRI scan as well.
