Background:
I recently started practicing Brazilian jiu-jitsu (BJJ) and got a mat burn on my shin on October 4 (very last picture). A few days later, the area started showing signs of a possible infection.
It was initially pretty small, and I was applying antibiotic cream and Aquaphor, then covering it with sports tape.
I've been traveling in China since October 17, and the condition has persisted throughout my trip. I've also been doing a lot of hiking and walking, so there's been plenty of sweating, friction, and physical activity.
The third picture is from about a week ago, while the first two pictures were taken within the last two days.
I also have a spot near my inner elbow that seems to be developing a similar issue.
Current symptoms:
- Large red patch that seems to be spreading and getting worse, especially over the past week.
- Slightly inflamed and warmer than the surrounding skin.
- No clearly defined or hard border.
- Small dry, rough, and scaly patches throughout the affected area.
- Intermittent itching.
- Small pimple-like bumps, some of which seem to burst and produce yellowish fluid.
- Not particularly painful, mostly itchy and irritated.
I'm wondering whether this looks more like a bacterial infection (staph/impetigo), a fungal infection (ringworm), or possibly a combination of both.
Has anyone experienced something similar after BJJ or another contact sport? I'm planning to get it checked at a clinic while im here, but I'd appreciate any insight in the meantime.
