I was laying down when I got a sharp pain on my right side. I was laying on my left side. I started to try and sit up, which hurt worse. I ended up getting up to go to the restroom, as the pain wasn't going away. The pain shot across my stomach and on both sides. This only lasted for about 20 seconds max. Any idea what this was? I've never felt anything like it before. Once it was over I felt perfectly fine.
