Hello ma'am/sir. This is regarding my husband's condition which he's facing from past 1 month. He is sensing some foul smell with eatables Or cooked food. He gets some unexplainable smell and not able to eat anything properly. The smell of onion, garlic, jeera, curry leaves, Aesopotida etc which has strong odour(flavor). He's loosing appetite and weight in turn. Want to know what might be the cause and how long it might take to recover. Note: He had severe cold and cough (allergic as dic said). This started after it's recovery. Kindly help with your valuable suggestions
