Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query about your husband and here is my advice.
Severe cold, feeling freezing, immobilized, feeling light headed, weak and breaking out in sweating indicate one of the following:
Viral fever.
May be associated with
hypothyroidism.
Other immuno-compromised states.
I would advise him the following in such a situation:
Consult a Doctor for a proper clinical evaluation, examination and necessary investigations so that we can get a proper diagnosis for an appropriate management.
Till then give him symptomatic treatment like Electrolyte solution.Ask him to stay indoor in a a comfortable bed with warm constant temperature.
Give
Paracetamol for symptomatic relief.
Once the clinical evaluation and investigations reports indicate the correct diagnosis he will be given an appropriate management.
Hope I have answered your query.
Let me know if I can assist you further.
