I was laying on the couch right arm on a rest. I sneezed and felt a real sharp pain in my lower right abdomen. I have a high tolerance for pain but this made me jump up and walk it off.  Still hurts a lot when I twist, Bend, cough, blow knose, sit...it just hurts. Did I tear something? What do I do.
Some time severe straining e.g. coughing, sneezing, vomiting can put intense pressure over abdominal muscles and can cause rupture of small vessels resulting in hematoma formation in muscle and severe pain. This can be treated only by rest and painkillers.
