I've had a similar experience in Covid with muscle tightness. It's unbelievable how much our bodies compensate. It started with a muscle injury to my upper back. Well to heal it, unbeknownst to my conscious awareness, almost an entire half of my body tightened to allow that one area to heal. Like you said it's as if whole sections of my muscles were numb as well, and only after repeated stretching did I "activate" those dormant areas. And it took being in a very calm and relaxed state (not trivial to do with tightness and/or pain) to "sense" these areas and being stretching them out. Turns out I had to find stretches for all the way down to my big toe to the top of my head and everything in between. The lessons of body to mind are overflowing suffice to say.
