I want to concur with what every one else has said. Not to alarm you, but please don't dismiss your symptoms!! Tam had a impaction that she was hospitalized several days for.
I know that when I have been inactive for several days I become constipated and have experienced symptoms similar to what you are describing. I have used a similar product as to what Liz was describing. I also use the ducolax and senna tea or tablets regularly. I also drink lots and lots of water and try to eat a high fiber diet.
I hope you are feeling better soon!!
