I have a slight ingrown toenail and every time I play badminton it gets red and inflamed. It is fine if I just walk around or not exercise. But during badminton it gets hot. My toe slides into my shoe and gets bump = ouch. Sometimes I hit my toe by accident = bump. After the games you can tell its red and swollen. "Cry" My doctor toe me, with badminton since our feet slides up and down it is more prone to ingrown. I'm not looking for a fix, but asking if anyone else have this?
