Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of viral upper
respiratory tract infection (URTI) is more likely.
Viral infection can cause
skin hypersensitivity and similar burning sensations in skin.
Usually these symptoms are self limiting.
So tell him to drink plenty of fluids orally.
Do warm water gargles and steam inhalation 4-5 times a day. Apply ice packs on affected skin areas.
Take levocetrizine tablet twice daily.
Don't worry, he will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
