Hard turtling or hard flaccid?

Hello,

I had an injury before Christmas. It made sensitivity go down, the sensitivity has recurred but is still lacking on top of the shaft.

I wonder, sometimes my penis turtles and becomes hard randomly, will this go away because I do not see any correlation as I am not doing PE at the moment? Maybe I am healing

Best wishes

Bumping this as I’ve noticed with myself that my flaccid turtles up and feels “hard” rather than soft.
