Hey all,

I've been posting on the anxiety/panic board recently but thought I'd post here as talking to people who actually know about allergies might be helpful. Lately a lot of my anxiety has stemmed from fear that I will react to medicine or food and suffocate from the resulting reaction. I currently live in a foreign (to me) country with somewhat questionable healthcare, so a lot of the medicine here isn't used at home and the food is different as well.

Basically I want to know how allergies work. Do life threatening reactions always manifest quickly (I often worry for hours/days after taking a new pill or eating new food)? Right now I feel a burning/itching all across my forehead and my throat feels tight (which might just be the anxiety response to the burning/itching) - I'm worried I'm having a reaction but I can't see a rash and I haven't eaten yet this morning - so nothing but water for the past 10 hours that could cause a problem. The doctor I'm seeing thinks my post-nasal drip and tight throat is caused by seasonal allergies so I'm currently taking Levocetirizine and a Corticosteroid for seasonal allergies - but I've been taking them for 2 days and this burning itchiness is new.

So from your experience, does this sound like a real allergy problem? Sorry if cross-posting like this is frowned upon - I'm new here.

Sometimes it response quickly sometimes it builds up to a point and then reacts.

Have you taked to the doctor about the burning and itching? The steroid should keep allergic reactions to minimum.

Classic allergies occur usually within an hour or two of contact with the trigger. But sometimes people can have delayed reactions that can take days or even weeks to show up.

But if you are having burning and itching, it could either be a reaction to something, or could be an infection (fungal or viral, most likely) -- steroids that work so well for allergies can make it so our immune system isn't able to respond as effectively against infections.

Be sure you talk to your doctor about your symptoms. Oh, and steroids can also increase the intensity of anxiety, so you may want to consider some relaxation techniques or supplements/herbs or meds for anxiety as well.

Thank you so much for the help - I will be sure to mention the burning/itching symptoms to my doctor the next time I see her. And I am indeed learning the importance of doing some sort of relaxation exercises - I will continue with those in case the steroids increase the anxiety.
