What Causes Allergic Hives On The Face Due To Cold Weather?

I'm a 59 year old female who two-three times a year experiences allergic reactions for no apparent reasons. They have occurred while sleeping, walking in either cold or warm conditions, or just sitting. My doctor has claimed I have a conditional known as a heat induced anaphylactic reaction. So far I have not experienced difficulty breathing during a reaction, but my body becomes covered with hives and my face will swell. Any insight would be much appreciated.

Hi,

Welcome to health car magic,

There can be plenty of causes for allergic hives or urticaria like drug allergy or insect bite or some viral infection or extreme cold or heat.

Generally urticarial disappears after few minutes without any treatment if it persists then you may require further treatment with antihisatmines like cetrizine or steroids and mast cell stabilizers.

So,if you are suffering from this then first thing you don't have to worry.

In majority of cases,It subsides by itself or you may take antihistamines like benadryl,avil,cetrizine etc and the rashes will go away.

The best way to avoid any allergy is complete avoidance of triggering factors.

You can consult dermatologist for further advise.

Regards,
