Can a jumpy knee reflex be normal, or is always a symptom of spinal cord problems?

In brief: Depends

If both knee reflexes and both ankle reflexes are "jumpy" it could be a thyroid condition.
If only one knee is jumpy, it increases the chances that it is from some problem with the nerves from the spine. If you have a weird ache near the outside of your thigh, that increases the chance it is from the spine. Please get it tested more thoroughly.
