No breathing problems or lightheartedness.

No swelling of arms/ legs, bar a wee bit foot/ankle swelling after periodic 20+ km pack walks/climbs.

Regular 8km pack walks and runs, no swelling at all.

No known history of autoimmune disease(extended family health issues have included lung cancer killing both heavy smoker maternal grandparents and lifestyle related diabetes contributing to death of paternal grandmother).

I haven't taken any antihistamines. No cold medicine(mostly just nose drops for closed nasal passages) taken in at least 18 months.
The timing and duration really points to one of the two diagnoses mentioned earlier (cholinergic vs. exercise-induced urticaria).

The other possibility is exercise-induced vasculitis, but that rash typically lasts days, not minutes to hours like yours.
