Hi Jelly,
It could also be the nerves healing as well & you’ve only recently had surgery. I had a WLE, but I do remember having some stabbing type pains when it was healing.
If you feel you need some painkillers, then do take them, there’s no right or wrong on this & we’re all different. Obviously, if it persists, it would be an idea to get it checked out for your peace of mind.
