Hi. Thanks for your query. Noted your history of constant headache, bowel movements more than usual and have found out that there is a mice in the house. I do not think these may be related unless you have been bitten by them. The most probable reasons can be intestinal infection with toxemia that gives headache. I would advise you the following in such a situation. Get a stool examination, blood tests and a clinical evaluation by your Doctor as you are suffering for a week, a long time. A course of an antibiotic should help you to get the resolution of the frequent bowel movements as well as headache. Take care about the food habits and have fresh home-made food only. Avoid outside foods and beverages strictly.
