Hi ritaac ~
That means the opening where the nerve comes through "foramen" is narrowed "stenosis". Sounds like you may have bone spurs at that level.
Foramen:
A small opening, orifice, or perforation. Used when something, e.g. nerve, blood vessel, notochord, passes through the opening. Plural foramina.
Stenosis:
A stenosis is an abnormal narrowing.
I hope this helps. If you have more questions please ask and some will try to help.
