How long after back surgery can scar tissue cause pain?

Usually 3 months. Usually this is no longer than 3 months unless the scar tissue causes nerve entrapment or surgery resulted in the development of a neuroma which may require additional therapy. First try a trial of scar massage if permitted by your surgeon.
Scar can be painless. In the past we often said if a patient didn't get better it was from scar tissue. I personally feel that this is rare that scarring around the nerves causes pain but rather the pain is due to the initial damage to nerve and may made worse by manipulation at surgery.
