Now it's often itchy, uncomfortable and hot below.

Rash appeared at the root of thigh, scrotum was itchy all the time, and the symptoms disappeared after taking tinea medicine, indicating that it was a fungal infection. Generally, taking medicine is very difficult to treat, because there is no medicine that is particularly sensitive to fungi at present, so it can only be delayed and will definitely appear again in the future. One way is to keep it clean. It's very hot now. If possible, I suggest you wash it every day, preferably with men's care liquid, and change your underwear frequently, not more than three days. When it is cold, wash underwear every other day, preferably not more than three days. If you have an attack, you should apply dyclonine or Pikangwang for at least three days. The main thing is not to put underwear and socks together in the future. You must pay attention to personal hygiene. That's all that matters.
