Anyone heard of it?

tigress said:Actually, now that you mention it, it's certainly not as bad when I use the elliptical. I always thought that was because the elliptical is inside as opposed to outside. Maybe it has something to do with what muscles we're using? Like maybe when you use certain muscles they get this reaction? I haven't taken gross anatomy yet so I don't know the answer to that question
tigress said:Well I get it too. Actually it can be extremely bad; my thighs will feel like they're burning up and itching. If I scratch (which I usually can't help, because it's awful) I get red dots (petechiae from scratching, probably). Either way the area becomes red, swollen, and very hot to the touch. Cold weather seems to make it significantly worse. I also get something similar, with more swelling, on my hands, particularly in spring and summer, which seems to be obviously an allergic reaction, but to what I don't know. In terms of the exercise, it doesn't happen as much if I'm in good shape. If I'm trying to get back into shape it seems to happen more.
I once asked an allergist about it and was told that it might be related to my autoimmune condition. But he really didn't know. I never used to think I was particularly predisposed to atopy in particular, but lately I've also developed mild eczema on my arms, so maybe I am. (Except I joke that I caught the atopic dermatitis from my husband )
Other than the obvious (http://www.emedicine.com/DERM/topic442.htm), the only thing I"ve really found is this: http://www.emedicine.com/ped/topic724.htm , which is pretty scary. If what I (and you?) am experiencing is early stages of this sort of thing, it's certainly important to be vigilant. I doubt that's it, though; it seems more annoying than dangerous. Regular cholinergic urticaria is more likely, even though it doesn't really fit for me -- no wheals, really, and it takes a while to develop, often developing only after I stop exercising, actually.
I'd love to hear if anybody else has any ideas. It does get extremely annoying. The other night I was walking around town for a long time, it was quite chilly out, and at one point my thighs were itching and burning so badly that I had to go behind a pillar to scratch them; a few days ago I actually bruised myself from scratching at it, but when it's happening I don't even notice because it's so excruciatingly uncomfortable.

Same exact thing happened to me once in Highschool. I forget which antibiotic I was on..... popped up when I worked out (b-ball season) and stopped a few weeks after.Pinesinger said:I had this problem for about a month, it was attributed to an antibiotic I was taking at the time. I broke out in very large red urticaria on my legs, especially thighs, lower arms, and face. It only happened when I exercised, and was worse when I was outside. After about a month it stopped and hasn't happened since, that was my first year of school, I'm now an MSIII. My doctor recommended Zyrtec to try to control some of the histamine, and actually suggested I carry an Epipen because she was concerned about this being a precursor to angioedema and anaphylaxis.
Jllander, i see you're in Winston-Salem, maybe it's something in the air here?
jllander said:Thanks for the feedback. I have heard of people allergic to their own sweat, which could explain my symptoms but the only weird thing is that I can be using the elliptical trainer, sweat like a pig, and be totally fine. This itching only comes on when I walk or jog. I found that article on exercise induced anaphylaxis too but I highly doubt that's what this is because it only happens with certain kinds of exercise. <shrug> I'm an medical oddity. Hehehe!

Strange but is is only mentioned once in the literature.
Duffull, S. B., and E. J. Begg. "Terfenadine ineffective in the prophylaxis of exercise-induced pruritus." Journal of allergy and clinical immunology 89.4 (1992): 916-917.
I get it - intense itching over my legs, butt, back, arms - when I exercise in a colder environment - mostly with running. It hurts actually. If I stop running, it slowly gets better. No rash, just increased flushing in the itchy areas.
I think it is genetic because my bro and sis get it too.
Again, it is strange the medical community is silent on this as I think a lot of people get it - it is described by people all over the net saying they get it - yet most medical sites seem clueless (blaming food, or calling it Exercise induced urticaria or anaphylaxis).
