Exercise induced urticaria (spots!)

1 watcher

Non-runner Sep 2018 2:24pm, 13 Sep 2018 174 posts	0 Non-runner To my horror I have suddenly developed exercise induced itchy spottiness, technically urticaria or hives. Following exercise, even if I don’t feel particularly sweaty, my torso is completely covered in small red bumps that itch like crazy and take hours to go down. It happens after even short runs or biking. Does anyone else have this and how do you deal with it? Will it ever go? Taking an antihistamine and dabbing calamine lotion on so far, plus have switched my laundry liquid to non-bio. Thanks.

I found ibuprofen could make me itch quite a bit, especially if combined with activity, and possibly, sunlight. I read HB's link and it lists anti-inflammatories as a possibly aggravating factor for hives. (Of course, I am now sitting here scratching away. I was fine before.)

I don’t take anti inflammatories but I do have a wasp sting allergy and it was alarming to me that I suddenly developed similar symptoms, for no apparent reason. I’ve exercised vigorously all my life and it has come out of the blue and I would quite like to know why it has suddenly started. Still, guess I will just have to live with it, as long as it stays on my torso I can manage it.
