Hello, your condition is folliculitis, which is mostly caused by local hair follicle blockage and bacterial infection. It usually manifests as pain, redness and swelling, and in severe cases, high fever and suppuration. It is recommended to take a rest and drink more water. Avoid spicy and irritating foods, and avoid squeezing the affected area to avoid spreading the infection. At the same time, you can use anti-inflammatory, heat-clearing and detoxifying drugs.
