<human>: I decided today was the day I start losing weight. It was my day off and I wanted to stay active. I usually take about 10,000 steps in a day, so I decided to try my best to reach that on my day off. I went for a 3 mile walk, and didn't notice anything. Now that I'm home and it's sometime later, I have a thumb sized patch on my thigh from where they rubbed while I walk. 

I have a history of getting rashes, but it's usually over a period of time. Takes a week to show up and a week to disappear, but this one was almost instant. 

I was wondering what I could do to avoid this in the future? Is there a certain type of underwear that would help me? Maybe powder or deodorant? 

Also, now that I HAVE the rash, what can I do to keep it from hurting when trying to work out? I know that I always try and find excuses not to work out, and I don't want this to become one of them.

Provide a brief overview of the text.
<bot>: My thighs rubbed together and now I have to walk like a cowboy. How do I avoid this in the future and deal with it now?
