Sometimes when I stretch, with my hands above my head and tummy out, my lower stomach hurts and I get a sharp pain going down towards my bladder into lady parts... It will be fine until I either stretch again, or go to sit/ stand. Did I just pull a muscle?
By your symptoms I am predicting you are not much active person. Our body and muscles tend to be loose and weak due to not exercising do when we suddenly tech out we tend to feel a pullout worry you will be fine
