This may be personal ? and unrelated but has it been a while since you have had a really good stool that can cause these problems as well i think. Hope you feel better
Hard to say.. Hardness and extension are usually the gas, and the trick is to see how long it last. Sometimes an irritation caused by foods or a virus can cause this. If you have a lot of pain, vomiting, fever or constipation, you should go to the doc right away now that it's been several days. If you start to get better, it could be a virus that will resolve.
