As the case may be, if it's ingrown toenails, it's useless to apply drugs. If it is inflammation caused by bacteria, ointment can be used. I have the experience of ingrown toenails. You can go to the drugstore to buy a scalpel, 10 yuan or so, with a blade on the handle and a bottle of alcohol. When I get home, I wash my feet with salt water first, then I hold back my pain, disinfect the suppurated place with a scalpel, and at the same time, I pricked my nails with the tip of a knife and cut them off with scissors. It will bleed during the process, so just wipe it with toilet paper. After the nails were cut off, the pain stopped that night. Finally, remember to disinfect with alcohol, and disinfect shoes with alcohol in the next few days. My paronychia is as serious as yours, and I caused it myself. Although it may happen again in the future, it is much better than pulling nails. I pulled out the nail twice, but it didn't work. I finally cured it in my own way. It doesn't hurt to wear leather shoes now.
