Folliculitis is an inflammation of the skin's surface, and this condition falls under the purview of dermatology, which can be treated at a regular hospital's dermatology department. This disease is related to excessive sebum secretion, consumption of spicy and irritating food, or frequent late nights. Prompt treatment is necessary once symptoms appear, and it can involve oral and topical anti-inflammatory medications. It is advisable to avoid spicy and irritating foods and try not to stay up late as this disease has a particularly high recurrence rate. If the folliculitis is relatively large, you can visit the dermatology department of a regular hospital for a minor surgery to drain pus. If it is small, local disinfection followed by using a needle to puncture and clean out the pus and blood may suffice.
