You can do a forum search for "scar tissue" if you want to find older posts/threads. a whole site search link is in my siggy.

I'd say if you were doing well for the most part and sx begin to increase again, scar tissue may be a factor, or perhaps postures/uses and/or slipping into bad habits.

I would get back into any good self care plan, or therapy that worked well for you before.

Some people just seem to produce more of it than others also, so that might be a factor also..
