Here is My Question:
I haven't had feeling in my feet in over 9 years. Why is it that I get horrible foot cramps that clench my muscles up for several painful minutes when I do something as simple as apply pressure to a certain part of my upper thigh or even scratch an itch in my lower back?! Am I weird?
You are not weird at all. Foot cramps and spasms can be caused my abnormal reflexes in your spinal cord that create spasms in the muscles of your feet (common in MS) or irritability of the muscles on the bottom of your feet (arch muscles) often spreading to your big toe. Foot cramps are very common even in people without MS. These can and often do occur even when an individual has no sensation in their feet. This is because the parts of your nervous system responsible for sensation (peripheral nerves and sensory pathways in the spinal cord) are separate from those areas responsible for cramping and spasms (muscles and motor pathways).
There are many causes and many treatments of cramps and spasms, so contact your doctor to get evaluated and find a solution.
