A week ago, I was a little itchy. I don't care. Today, I saw a piece of red pimple. Is it serious? Is it contagious? Can you cure it?
If there are obvious small red pimples and certain itching symptoms in this part, it should be considered that it is caused by fungal infection. We can also call it tinea cruris. Most of them will be accompanied by severe itching symptoms. They should be actively combined with antifungal drugs.
According to the symptoms you described and the pictures you sent, the skin lesions at the root of the thigh may be tinea cruris caused by fungal infection or eczema. In this case, you can go to the dermatology department of the hospital, do dermatoscopy to make a clear diagnosis, and select appropriate drug treatment according to the examination results. Usually pay attention to local hygiene, avoid contact with irritants, and wear pure cotton breathable underwear.
