Hello welcome to 'Ask A Doctor' service.
I have reviewed your query and here is my advise.
I appreciate your health concern about your husband, he may be suffering from
andropause symptoms in which the testosterone levels are fall slowly with age but in few cases they fall abruptly lead to a sensation of warmth that comes on suddenly,heavy sweating and reddening of the skin. Treatment with avoid alcohol,
smoking,coffee, spicy food,warm room temperatures,tight or heavy clothing.
So you may need to get it done serum testosterone levels, use if it is low need
testosterone replacement therapy. Use alternate medication under your doctor guidance in case of
prostate malignancy.
If symptoms not improved please consult your doctor he will examine and treat you accordingly.
Hope I have answered your question.
