Tail bone fractures are notorious to pain management. Avoiding proper practice of care during initial few months of injury may lead to longer discomfort. With proper followup this can be tackled, just have to be patient.

As it is four months since injury, Start physiotherapy and exercises. Use a soft pillow to sit and check your calcium and vitamin D3 levels. If its not controlled by these then consult a spine specialist. Last option to treat condition would be surgery

Use a donut pillow for sitting, pain will be there untill the fracture unites especially if you sit on a hard surface. It may take a couple of months for pain to subside
