Like you, I am also around the ring finger nail, but it is on my left hand, which does not affect the use of my right hand.
At that time, the place where I lived was humid and I developed some pimple-like urticaria on my body. The doctor said it was not serious and it was just a common skin allergy, so he prescribed some medicine (it cost me more than 200 yuan, it was really bad!~). When I went to the doctor, I was told that I had a small patch of sweat rash on my left hand. Is it okay to use Parexone? The doctor said it is okay. It turned out to be useless. Later, the urticaria disappeared, the sweat blisters became more and more frequent, and it started to itch.
I looked at the ointments for treating urticaria, and one of them called "Desonide Ointment" can treat sweat herpes, so I applied it twice a day (strictly enforced), and the result was that the same day It was effective, the itching stopped, and the color of the blisters became darker. After a week, they were healed and the dead skin was gone. But I don’t know if it will relapse next year. It is said that it happens every year. This disease is not contagious or hereditary.
Be sure not to get wet, otherwise it will grow a lot and quickly.
I don’t know if this ointment is good to buy. It seems to cost less than 40. I bought it in Shanghai.
There should be some in pharmacies. There are also a few words "Fangyanzhuo" on it, which should be trademarks, produced by Chongqing Huabang Pharmaceutical.
I wish you a speedy recovery.
