Patient discussion about urticant.

Q. I was diagnosed with chronic urticaria. What is the reason for this condition? I was diagnosed with chronic urticaria last week after more than two months of urticaria (I have more than twenty 1 dollar coin area no my trunk that are red swollen and itchy). when I was younger I had a similar reaction too a bee sting and I was treated with an adrenalin shoot. Since that one time I never suffered from this kind of symptoms till two months ago. What can be the reason for this condition?

A. As was said before chronic urticaria is a symptom of many problems. I once took NSAIDs for knee pain and I started to itch myself. It took my doctor 3 weeks to understand that I was allergic to this specific drug. I also know that tomatoes can cause me an allergic reaction. Try to think is there anything new in your life? Tell it to the GP maybe he will be able to tell you if this is the reason for your symptoms.

Q. What can cause an angioedema on 15 year old girl? I’ve been getting angioedema signs on my left arm for the past few weeks, not severe but it itches and sure don’t help my low-as-it-is self esteem…

A. The following may cause angioedema -

Animal dander
Certain medications (drug allergy)
Emotional stress
Exposure to water, sunlight, cold or heat
Foods (such as berries, shellfish, nuts, eggs, milk, other)
Insect bites
Pollen

Hives or angioedema may also occur after an illness or infection.
Try to see if you were exposed to any of this and report it to your Dr.

Q. What caused my hives? I woke up this morning and saw that all my back and chest are covered in hives. How did this suddenly appear? What caused it?

A. Urticaria (hives) is generally an allergic reaction, or an immune response to food or some other allergen, but can also appear for other reasons, notably emotional stress.
