Hello, I read carefully your query and understand your concern. Your symptoms seem to be related to a tailbone cyst. A tailbone cyst is also called a pilonidal cyst. These cysts are caused most often by an ingrown hair. A hair grows back under the skin or skin grows over a hair. It causes redness and swelling in the area of your tailbone in or just above the crease between your buttocks. I suggest using anti inflammatory medications such as Ibuprofen to relieve the pain. I also suggest using warm compresses for local application.The heat will help pull out the pus, allowing the cyst to drain. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards! Dr.Dorina Gurabardhi General &Family Physician
