Is it normal to get exhausted during allergy flare ups?
Patient: I had raw almonds last night, and I have never had a problem with them, however, I noticed my lips started to tingle and my throat began to get sore.  I noticed it an took benedryl (since I do have other food allergies, I new the symptoms). I then slept for the entire next day...as in 24 hours.  Every time I have an allergy flair up, I am usually exhausted.  Is that normal for someone to experience? Doctor: Hello,Welcome to HCM,The allergic reaction means when you are exposed to the triggering factor like dust, mite, pollen and food to which your allergic, there will be release of mediators of allergy like histamines which will produce all the symptoms of allergic reaction.As you are known case of allergy these are the routine phenomenon to occur in your body, when these symptoms occurs it will make  you exhausted and tired. If you test your blood for absolute eosinophil count during the allergic reaction there will be increase in the count.The medicine like benedryl will help you to control the symptoms but it is not going to prevent further occurrence of allergic symptoms.So I would suggest you to undergo skin prick test for the most prevalent allergens and identify the allergen causing all these symptoms and then you can avoid the allergen or you can take immunotherapy.Thank you.
