The only commonality between episodes is running, and perhaps pushing myself harder than usual or maybe eating too soon before exercise (I do not have food allergies otherwise). It starts with itchy/burning palms, then swollen lip and hives. It happened on an outdoor run in winter weather, in high sun in summer, and a few times indoors at Orange Theory. I exercise 3 times per week but it only happens twice a year or so.

For me, it doesn’t happen every time I exercise, so I am not sure what triggers it exactly but it happens at times when I run.


I know someone it happens to from running too, but only a couple times a year. Have you noticed any commonality in episodes?

Could this be a manifestation of some other illness besides an allergy reaction?


Histamine reaction. Various causes.

Check your organ health, such as your liver.

Exercise more.

If you are in perimenopause it’s possible your body is responding more acutely to things that never triggered you before.


I was going to say this, too. I broke out in hives and an itchy, blistering rash due to pregnancy hormones. It’s how I knew to take a pregnancy test the last time! Taking Zyrtec for several weeks helped.

Ask your doctor about hereditary angioedema (hae) as a possibility.

You need a prescription for an Epi-pen. I’m not saying you need to use one today, but any propensity for allergic swelling of the airway (including your lips) merits keeping one around.

You may have idiopathic urticaria (hives of unknown origin) or there are some genetic conditions which basically only cause occasional angioedema. Speak to your doctor.

google chronic urticaria and see if that fits. take a non sedating antihistamine every day and see if that helps
