Is cauda equina syndrome caused by epiderual?

Rarely: Cauda equina syndrome occurs with severe compression (pressure) on the nerves in the low back. People have trouble emptying the bladder, numbness in the private area; they may also have leg pain (usually both sides), numbness, tingling, weakness. For an epidural injection to do this, a large volume of liquid would have to be injected; if the nerve channel was already very narrow it could happen.
