I've been running for around 8 years, but the past few months have started getting an occasional allergic reaction when running. Starts out with skin feeling increasingly hot and itchy, then welts all over my torso, and face swells up like Mr. Stay Puft. Usually piriton will cure it in around 30min, but last night I had an extreme reaction, and totally lost my vision and became delirious, felt like I was going to pass out. Luckily I'd been to the allergy clinic at Royal Brompton the day before and they'd given me an EpiPen (adrenaline injection), which fixed me, but took an hour to get close to feeling normal again. Paramedics came and my bp was dangerously low, but gradually came back to normal levels after the adrenaline shot. Would be interested to hear if anyone else has any experience/advice. Gonna ask the doc for a big stash of EpiPens to take to London next week!

Not sure I can quit running because of this, just need to make sure I'm always prepared and have the meds to deal with it as and when it happens. The scariest part about it is if it comes on when there's no one else around. Needed my wife to call the ambulance last night as I couldn't see or speak!

Have been keeping a log of what I've eaten every day that it's happened, only common thing so far is chilli. But I've never had an issue with that before. Thought it might also have something to do with the unusually cold winter we've had, but it was relatively mild yesterday evening. Maybe it is purely exercise induced
Michael TwithaP Apr 2013 10:29am, 12 Apr 2013 First-time poster!!	Quote Pin Michael TwithaP I was diagnosed with this several years ago.....been a lurker on the forum for ages but have just registered having seen this to comment!! I had all sorts of blood tests and that but they were never able to find any allergies or anything. I believe I am allergic to my own sweat and that is what brings on the hives and the initial reaction. When I run for over an hour and leave sweaty clothes sitting against my skin, the hives always develop around the damp patches. I have been able to keep it under control so hopefully it won't stop you running. Anti-histamines keep mine under control, just pop one each time I train heavily. I have a repeat prescription for them.....

Running through an anaphylactic reaction that appears to be escalating in severity and has required adrenaline might be less wise...
