I went to a BJJ class for the first time in a long time a few days ago. I went to a new gym to try it out and see how I liked it, went to the nogi class. I sweat a lot, came home, took a shower not too long after, and went to bed. The next day when I went outside and it's hot out, very quickly I felt a slight sweat (not visible at all) and also began itching like crazy.
This has continued since. Whenever I begin to sweat or just randomly I start to feel this needle-like itch. It is mainly in areas that were exposed when I was grappling, such as hands, feet/ankles, lower legs, face, and lower arms, as all I was wearing was a shirt, shorts, and boxer briefs.
It's driving me crazy because I can't do anything physical or even stay outside for more than 2 minutes (I live in a hot area) without breaking out in this unbearable itch.
I would say maybe it's this new soap I've been using, but I have been using it for weeks before this happened and had no problems. However, I have started using a different laundry detergent.
If you think you know what might be the issue or solution please help!
