> used me to change my routine and avoid certain activities which only exacerbated the issues, which led to more avoidance. Eventually I couldn’t walk.

Anecdotally, I had a phase where pretty much the same thing happened to me with the Achilles (+ calf/ankle) flare-ups I was having (during this part of my chronic journey). Eventually got through it by doing small walks around my home, then outside but keeping the frequency high each day (i.e. instead of 1 "long" walk, doing 3-4 short ones). I.e. Desensitisation / daily movement

Splitting up activity to bite sized chunks was critical for me as well. It prevents over straining but I think more importantly it also prevents you from being stagnant for an extended period of time.
