A small swelling or discomfort near the tailbone may seem harmless at first, but it can sometimes indicate a pilonidal sinus. Ignoring the early signs may lead to infection, pain, and difficulty performing everyday activities. If you notice recurring discomfort, swelling, or drainage near the base of your spine, consulting a Pilonidal Sinus Doctor in Ghaziabad can help you understand the cause and explore appropriate care before the condition worsens.
