Hi, I am new here. I am in my early 40's and recently started watching my food in take in hopes of loosing my excess weight. (between 20-30lbs). I wanted to get back to working out, and decided to start walking. I have been out a couple of times, but once I have walked fast for about 10-15 minutes my thighs and lower back (mainly) get an incredible itch, that increases as I go. I usually turn round at this stage, heading for home, and by the time I get there, Its unbearable, and my skin is all read and hot.
Obviously, I don't go out walking anymore, and wont till I have this solved. I have asked about this elsewhere but got no answers. does anyone know what this could be from or how I could solve it?

GREAT question I get that feeling too but when I run... it's like my legs are on fire. So far no one has been able to answer me why.

I had a similar problem - I would get hives on my thighs that itched when I walked fast or jogged. Although, mine became very noticeable once I stopped and was at home. I tried SO many things to get rid of this problem - I'm not sure which one specifically worked.... but now, my hives are tiny, if at all - and I don't itch.

Buy lighter clothes made specifically for joggers- meaning stay away from 100% cotton.

Use a non-allergenic washing detergent.

I stopped eating dairy (maybe experiment by eliminating foods that are known for causing slight intolerance... dairy, gluten, soy).

Good luck - its an annoying problem!

Well I am glad to know that Iam not alone in this.... I am so impressed that you kept on going regardless
I am seriously worried that if it happens again I might rip of my clothes in the middle of the street...

I get these red marks on my legs when I exercise. I asked a doctor once, and he said it's just the increased blood flow from the increased heart rate. It would itch really bad! Almost looked like under the skin hives! Especially if working out is new to you. You may have to do an elliptical workout to help with your problem. It's still a great workout! Or try swimming. I knew a girl who was allergic to exercise she would get hives all over her body, face, back, EVERYWHERE! She couldn't exercise at all if her body temperature or heart rate went up to a certain degree. So she dieted and still lost weight. I would consult a physician. Best of luck to you!

When I started running I used to get this itch on my legs and scalp too sometimes, I just chalked it up the blood circulating through my body and my not being used to it. It eventually went away... Sometimes I also think it's the salt from the sweat.

I get the same thing. It gets really bad if the room temperature is too low. Yes, it gradually went away after a few months, but I hated it and couldn't do much in the beginning. Now, instead of running I do workout videos. They help me exercise harder and longer without any itch or hives or heat.

I get hives easily: rapid changes in temperature, stress, and mildew are big triggers. Benadryl helps tremendously, but it also puts me to sleep. I use it when I just can't stand it. As I have gotten into better shape, it has gotten much better, but even now I have a scattering of light hives all over my body after I exercise. They don't itch or anything.

I'd rule out any allergic reactions to clothing fibers, detergents, etc. Unless you are getting true hives, I expect it is from blood flowing to areas that aren't used to being worked. I'd keep up the work and see if it eventually gets better. Get that oxygenated blood flowing, sistah!!

Good Luck!

Oh TG! I thought it was only me being weird! I don't get it bad, and not every time. Usually it is just a light annoying itch right on my jelly rolls and tummy. It usually goes away after a few mins for me... But I am so glad to hear I am not the only one!

Yup, my legs always itch when I run/fast walk for exercise. And now with hot yoga the tops of my hands/wrist creases itch like crazy. Ridiculous!

Well... I don't know if it's the same with you guys... but I have cholinergic urticaria. If I don't push through it, and I am just doing something that will elevate my temperature without keeping myself moving (for example, a long walk vs running and walking), I break out in hives all over, feel extremely itchy, and will often also become faint and nausious. Not that I'm doing anything overly strenuous in the exercise... it's just some of the symptoms of the urticaria.
