Respected sir, My father is around 60 years old. He is a serviceman. Yesterday night after dinner he suddenly started sweating, although it was rain and weather was cool.In dinner he took milk with rice, curry as usual. After dinner he felt little pain in stomach. We became very worried about sudden sweating. But sweating was not so profuse. So sir I want to know that what is the reason behind this sudden sweating? Please let me know. His blood pressure is almost normal. Around 120/85. He has no blood sugar. His weight is approx 58.
