<s>[INST] My doctor said that I have a hernia, but it didn't rise above my skin when Iwas laying down, so shewasn't really worried about it. Can a hernia move around in your body? I sometimes get a very hard knot in my abdomen that moves from side to side and/or up and down into my chest area. It sometimes is very painful, and sometimes it hurts so bad that I could cry. Now, I can feel it even when I am standing. It's like a hard knot. [/INST] Welcome to HCM.According your history you might have inguinal hernia.Some part from abdominal cavity comes out from the weak part of abdominal wall.It can only treat by surgical treatment.It is better to plan surgery before any severe development. </s>
