That would be a nightmare.<br /><br />I have cholinergic urticaria, so I know first-hand how frustrating these urticarias are to deal with.Cholinergic Urticariahttp://www.cholinergicurticaria.net/noreply@blogger.comtag:blogger.com,1999:blog-2057269305378114997.post-46947443316001935002010-04-06T22:06:32.205-04:002010-04-06T22:06:32.205-04:00From Google Buzz:

(Not now of course, this is San Diego after all). ;) 1:50 pm<br /><br />Vamsi Balakrishnan - Dermatographia urticaria I think is the most...interesting allergy-related condition that I've learned in med school so far. <br /><br />http://upload.wikimedia.org/wikipedia/commons/thumb/4/42/Dermatographic_urticaria.jpg/800px-Dermatographic_urticaria.jpg 3:15 pm<br /><br />Ves Dimov, M.D. - Dermatographism is actually not "true" allergy. The release of histamine is triggered by a physical stimulus (pressure) rather than specific antigen binding. 3:19 pm<br /><br />Vamsi Balakrishnan - Ah, didn't really think of it that way. I just remember learning it's the most common urticaria...and the pictures I've seen are...interesting always. <br /><br />So, a true allergy is always defined as "release of histamine from mast cells due to IgE allergen binding" but not any other cause (rupture, etc.)? 3:28 pm<br /><br />http://www.google.com/buzz/110859855629071891085/GXZiMYAAotZ/Cold-Urticaria-in-the-New-York-TimesAnonymousnoreply@blogger.com
