Any family history of autoimmune disease?
If you take an antihistamine (diphenhydramine or acrivastine) prior to exercise does the rash still occur?

Really centred on lower legs and inside of arms. Nothing else seen, and the wife has had a good look when I've had the odd breakout.
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.
