Pus is actually a natural response from your body's immune system. When your body detects a threat during an HS flare, it sends white blood cells and other immune cells to the area. These cells work to fight off what your body perceives as an intrusion, and in the process, create pus - which is a mixture of these white blood cells, damaged tissue, and other immune cells.
In HS, these pus-filled bumps often appear in areas where skin rubs together, like the groin area. They can start small but may develop into larger, painful lumps within days. Common characteristics of these pus-filled bumps include:
• Tenderness or pain when touched
• Swelling in the affected area
• Pink or reddish appearance
• Yellow or white centers that may open and drain
• Potential unpleasant odor when draining
Remember, while seeing pus can be concerning, it's a normal part of how your body responds during an HS flare. However, if you notice bumps that keep returning to the same areas, it's important to discuss this with your healthcare provider to ensure proper treatment.
