Symptoms of an allergic reaction vary depending on the body part affected and the severity of the reaction. Some reactions affect many areas, while others affect just one area. Reactions to the same allergen vary by individual.
Spring is in the air. Literally. From weeds to spores to grass and tree pollens, the warm weather is almost here, driving airborne allergen levels through the roof. That means your allergy symptoms -- the sniffling, sneezing, and itchy eyes -- are in overdrive and apt to stay that way for months.
What can you do? WebMD asked some of the country's leading allergy experts to weigh in with answers to your top questions about spring allergies. Here are suggestions for helping you find some much-needed...
Anaphylaxis is serious, potentially life-threatening allergic reaction which is rapid, or sudden, and potentially life-threatening.
One sign of anaphylaxis is shock. Shock has a very specific meaning in medicine: the organs of the body are not getting enough blood because of dangerously low blood pressure. This drop in blood pressure happens when the large blood vessels suddenly expand. If the drop in blood pressure is sudden and drastic, it can lead to unconsciousness, even cardiac arrest and death.
The person in shock may be pale or red, sweaty or dry, confused, anxious, or unconscious.
Breathing may be difficult or noisy, or the person may be unable to breathe.
