I haven’t had any surgery, but have injured my back through work and I too feel the more I ride the better it is(go figure) and during the off season (summer) it seems to be worse for wear.
keep mobile ride your bike, best of luck, seek more advice, even physio’s and chiropractors, or eastern medicin like acupucture. ps the mother in law had surgery and it looked like she would never be the same again, but it worked out well, and you would not know she has had a couple fused together.
