Braxton hicks feels like a tightening sensation they are irregular and uncomfortable but not painful. Labor contractions are painful and come at regular intervals feel like bad menstrual cramps neither sound like the shock you are having that reminds me of round ligament pain that I would have when I would stand up or move the wrong way...check with your doc to be on the safe side
Sounds like my braxton hicks.
Hmmm I'd ask your Dr about that. I've never felt the shock just tightening or cramping.
