Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of
viral fever with generalized
malaise is more.
So ask him to follow these steps for better symptomatic relief.
1. Drink plenty of fluids orally and keep yourself hydrated.
2. Avoid oily and spicy food. Avoid junk food.
3. Do warm water gargles 5-6 times a day.
4. Take combination of antihistamine and anti inflammatory drugs.
5. Apply warm water pad on affected areas.
Do all these for 2-3 days. If he is improving then no need to worry.
But if he is not improving then
consult doctor and get done clinical examination and blood reports to find out cause for fever.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
