Is It Normal to Feel the Coccyx Through the Vaginal Wall?

The coccyx can be palpated through the vaginal canal?

A few months ago, I had a fall and experienced pain in my coccyx, but the pain subsided after a few days, and I didn't seek further medical attention.
Today, I noticed that I can feel the coccyx bone through the posterior vaginal wall.
Is this normal? (I don't recall being able to feel something like a bone there before.) I also tried to push what seems to be the coccyx bone back inside the vagina, and I definitely felt soreness in that area.
I visited an orthopedic clinic today, but the doctor said that since there is no pain, they wouldn't perform an X-ray or any examination.

Hello, the vagina is separated from the coccyx by the rectum, and the distance is quite significant.
What you are feeling is likely not the coccyx.
The soreness you are experiencing may be due to ligament strain.
It is advisable not to do this frequently, as it could lead to inflammation and increased pain.
If you feel a protrusion or hard mass when palpating from the vagina towards the back, I recommend consulting a gynecologist for an internal examination.
Gynecologists also have transvaginal ultrasound available to help clarify the issue.

More Info

Feeling the coccyx (tailbone) through the vaginal wall can be concerning, especially if this is a new sensation for you. Given your history of a fall that resulted in tailbone pain, it is possible that the fall may have caused some changes in the surrounding tissues or structures.
The coccyx is located at the base of the spine and is typically covered by soft tissue, including muscles and ligaments. In some cases, if there is a reduction in the surrounding soft tissue due to trauma, surgery, or other factors, it may become more palpable. This could explain why you are now able to feel the coccyx through the vaginal wall.
However, the presence of pain when you attempt to push the coccyx back may indicate that there is some inflammation or irritation in the area. This could be due to a number of reasons, including:
1. Coccydynia: This is a condition characterized by pain in the coccyx area, which can be exacerbated by sitting, standing, or certain movements. It can occur after trauma, such as a fall, and may lead to sensitivity in the area.

2. Pelvic Floor Dysfunction: The pelvic floor muscles support the pelvic organs, and any trauma or changes in the area can lead to dysfunction, which may cause pain or discomfort.

3. Infection or Inflammation: If there is any underlying infection or inflammation in the pelvic region, it could lead to increased sensitivity and pain.

4. Structural Changes: Sometimes, after trauma, there can be changes in the alignment or position of the coccyx, which may make it more prominent or sensitive.

It is important to note that while the coccyx can sometimes be felt through the vaginal wall, if this is accompanied by pain, discomfort, or any other unusual symptoms, it is advisable to seek further medical evaluation.
Since the orthopedic doctor you visited did not perform any imaging due to the absence of pain, you might consider consulting a specialist in pelvic health or a gynecologist who can perform a thorough examination. They may recommend imaging studies, such as an X-ray or MRI, to assess the coccyx and surrounding structures more closely.

In conclusion, while it may not be entirely abnormal to feel the coccyx through the vaginal wall, especially after a fall, the associated pain and discomfort warrant further investigation. Seeking a second opinion or consulting a specialist may provide you with the answers and reassurance you need regarding your symptoms. Remember, your health and comfort are paramount, and it is always better to err on the side of caution when it comes to unusual bodily sensations.
