Oh absolutely! I got severe HS breakout both under arms from water aerobics. The chlorine broke down my skin barrier and my exercise arm movements caused friction which caused the breakout. On top of that I used roll on deodorant so every time I got healed I’d get staph infections from my deodorant. I quit the gym. Also their germ protocol for machines wasn’t good. Years later decided to try gym membership again. Having HS in pubis. But actually had some minor bumps before joining this second time. So not sure the gym is playing into it this time. But I know for sure it did the first time. Gyms are bad about carrying MRSA so I’m double afraid of gyms. Thinking about just exercising at home. Even if the machines are cleaned, no one cleans the heavy weight plates we have to put on and take off certain machines and it’s a lot of work to clean up every single thing at every single station. With this disease as bad as it can get, not sure it’s with the risk anymore.
