Go to a hospital with a dermatologist. Me too. I'm fine now. I have been treated for a long time. The most important thing is to kill fungi. The doctor will prescribe medicine. I took two boxes of that medicine in a row. 78 yuan, I'm fine now. Besides, I have to sterilize my shoes and socks at high temperature and get into the habit of changing socks every day. Basically, I don't need an injection If I go to a specialist hospital, small hospitals will give priority to injections. It doesn't seem to have any effect, but it takes the symptoms rather than the root cause.
