After about 3-4 minutes of running my torso will start to itch and this itch will then slowly get worse and spread to the tops of my legs. Then, after about 10 minutes, it subsides. The funny thing is this doesn’t happen if I do weights, row, swim or cycle even though I push myself just as much while doing these activities.
So, anyone know why I itch when I run but not doing other exercise? Plus is there anything I can do about it? It’s uncomfortable and though I like to run I often choose not to do it because of the itching.
In addition to the other posts, I find I have a few shirts that will cause that (doesn’t go away until I get really sweaty). Oddly the shirt ingredients appear to be the same or very similar, but the quality of the textile must be a little rougher or something. Try a different shirt? No shirt? Maybe a tighter or looser shirt?
In my (weak) defense you probably have more torso movement while running (esp vertical). Cycling and rowing are relatively stationary in the torso area. Also, I find I tend to heat up faster while running, though if your rowing and cycling are on trainers indoors then that shoots that theory down too. It find it very easy to overhead on a bike trainer indoors, even with fans.
If it’s an indoor/outdoor thing maybe some sort of allergy is involved?
When I first started taking up walking-as-exercise, I would get red itchy, burning thighs about five minutes into it. I read that it could be an allergic reaction so I started taking an anti-histamine right before leaving. It worked.
Now that I’ve been walking on a regular basis, it doesn’t happen anymore. I imagine if I took a long hiatus and then started up again, it would come back though.
