Hi I woke up with my body aching and with diarrea. I didn't exercise Yesterday at all. Only one thing the car hood fell on my head yesterday?

See a doctor. i do not think there is a connection between the head trauma, and the body ache and diarrhea. your symptoms suggest a viral illness. hydrate yourself well,take tylenol (acetaminophen) ,or ibuprofen. rest and eat only liquis, eat more yogurt and banana. treat the symptoms. go and see a doctor. good luck.
