I heard a lot of people say that you only have a SV when you have unbearable stomach pain... I'm not sure what this is, but I was fine for a while and then when I moved around - like, twisted my torso to look over my shoulder - a really sharp pain and N hit. And now I'm having a panic attack over it... I feel a bit better in terms of pain, but still very N. Is that normal? Is there something wrong?
