Hi, how are you doing today ?
As for your question , if you are so sure that your perineum is torn then go for a gynecologist consultation.
She will examine you properly and promptly treat it, this will also help in better and fast relief.
As for points to help healing take a nutritious food rich in vitamins like citrus fruits and keep the part
clean ( to avoid any infection).
Hope this clears out your question, hope to converse with you again.
Have a nice day.
