My sister has been diagnosed with congenital spinal stenosis. what is the likelihood that i also have it?

Possible: The condition runs in families, but doe not follow simple mendelian genetics (what you may have learned in high school biology). The size of the canal or channel containing the spinal cord and nerves does vary from person to person. The smaller it is, the more likely a person is to have problems during life. Seek assessment if you have arm or leg numbness, tingling, weakness; or unsteady walking.

You won't: You won't get it unless you think and thrive on this thought of getting or having it.
