Numbness in the toes, feet, or legs
Problems with thinking, such as confusion or poor concentration
Mental problems, such as depression or irritability
Headache, seizures, or stiff neck
Incontinence
Tremors, or weakness

[Revelation 911]

I have all but incontinence - thank God - but they are all from other conditions
