My husband told me he had nausea, hallucination, chill, headache, sleepless, dizziness, and body shaking last dark. He wanted to run a rest first before he see a doctor.So now he is sleeping. He seem little bit better now, What considerate bacteria rationale those symptoms?Body shaking, headach, restlessness..?
Find out if he has be taking any medications or other substances (i.e. drugs, alcohol, etc.) lately. Some drugs must not be taken on an empty stomach or mixed next to other medicine.
Find out if he have eaten or drank anything unusual (i.e. food from a unknown restaurant, expired milk products, meat, sushi, etc.).
Find out if he has be under a great deal of stress recently. Prolonged stress can own a very cynical effect on the body.
If the symptoms last for 24 hours and do not restore, contact a doctor immediately.
It could purely be the flu, but eliminate adjectives other possibilities first and do not ignore his condition, check on him periodically and see if he is breathing regularly.
I hope he feel better soon. He is lucky to have someone similar to you who cares so much something like him.
the flu
Sounds like probably a impossible flu - which means it's a virus and not microbes. Keep a record of his symptoms and his heat and get contained by touch with a doctor or pharmacist who can best advocate on a course of treatment.
Make sure he get's plenty of fluids (water and herbal tea, juice).
