A 34-year-old member asked:

is orange allergy to the inside or to the peel?

Either or birch tree: Reactions to orange can be either to the peel or the pulp (the fleshy part of the orange). Many people who have only itching in their mouth & throat after eating oranges and other raw fruits and vegetables actually have oral allergy syndrome. Oas is caused by allergy to birch tree pollen and the immune system mistaking fruit proteins for pollen allergens. Which one is your problem?

Can christmas trees trigger childhood allergies?

4 doctor answers10 doctors weighed in
Dr. Bert Mandelbaum
Pediatrics 24 years experience
Yes: They can, but not as often as you might think. People can be allergic to tree pollen and sap. In december, christmas pine trees do not release that much pollen, though they can be covered in pollen just from being outdoors for years. Many experts recommend spraying the tree down with water in the yard before bringing it into the house.

Depends: Depends on the type of reaction. Swelling (angioedema) usually lasts 24-72 hours when it reaches maximum. Allergies can last for very long times if not treated. If unsure, the safest bet is to see your friendly allergist for advice and treatment.

Could allergies and exercise induce asthma?

2 doctor answers5 doctors weighed in
Dr. Brian Bezack
Pediatric Pulmonology 18 years experience
Yes: Allergies and exercise are 2 of the most common triggers for exacerbation of asthma symptoms. If your asthma is not well controlled and you have allergies, treatment of the allergies is an important part of asthma therapy. If exercise is making your breathing worse it doesn't mean you can't do it. It suggests that your asthma is not well controlled and this should be discussed with your doctor.
