Recently, my friend (male) always feels itchy on his testicles when he sleeps at night, and the groove where his testicles meet his thighs is also itchy. How's it going?

This is not a big problem. Don't worry, it's mainly the groove where the testicles meet the thighs. Just apply triamcinolone acetonide and econazole cream (Fu) several times. I didn't know why this happened before, but it recurred. Later, I went to the hospital and the doctor prescribed medicine for me. The effect is very good, usually pay attention to cleanliness, and wet environment is also prone to problems. The itchy place is a little smooth, and a little dandruff will fall off when digging. I think it should be the same as my previous one. If you have any questions, please communicate again.
