At my highest weight of 291 I never experienced any chaffing or rash from being heavy. My weight is 254 and now I'm having a rash and chaffing on my breast and stomach and it's very itchy !! Is this surgery related ? Has anybody else experienced this please I need answers

You might have developed a yeast infection. I had one in my belly button!

So, see your doctor. One, see your doctor to get yourself fixed up. Two, be glad you have rashes because it's good to have a record of them for down the road. Most insurance companies won't help you with any sort of plastic surgery unless you can prove skin problems. (Yes, lemonade from lemons.)

Until you see your doctor, keep the area clean and dry. Cornstarch can help. And try not to scratch.
