Sometimes--I think I responded to you on another post regarding cyst?

Sometimes yes --if its from herinations or disc in the spine start to degenerate and make the foreman more narrow. If yours is from the cyst its not ness permanent stenosis-- like from spine disease. The neural foreman is the hole on both right and left side of a disc where the nerve passes thru -----it can get blocked from herinations or brown growth or ddd disease. I think you have impingement caused from the the cyst.
