My 20 year old quadriplegic, CP daughter has always dealt with constipation. Off and on she points to her belly and complains of stomach pains. Her stomach muscles are very toned, but where she points, I do feel a slight bulge. She also has been vomiting off an on, we don t know for sure what causes it, but she does point to her belly and the small bump , the size of a golf ball. Do you think it could be a hernia from a lifetime of constipation?
