Endometriosis is a condition in which the inner lining of the uterus, also known as endometrium, starts growing abnormally at different locations. These locations may be outside the uterus and in other reproductive organs.
Endometriosis is associated with severe pain, but it may happen that people with advanced forms of endometriosis may not experience any pain. Nonetheless, endometriosis is still considered a painful disease. So let’s see what causes pain in this condition.
Endometriosis can arise at multiple spots

When endometrium grows in the muscular region of the uterus, it is known as adenomyosis.
If it grows in the ovaries, it is termed chocolate cysts.
If found in the area between the vagina and rectum, it is called deep endometriosis.
There are 2 types of cases observed with endometriosis:
- Some women have severe endometriosis but have no pain symptoms.
- Some women suffer from intense pain without having deep endometriosis.

Causes of Endometriosis Pain
Here are the main reasons for having pain in endometriosis:
1)The uterus is connected to the fallopian tubes on the upper right and upper left sides. The ovaries are linked to both sides of the fallopian tubes. Underneath the uterus lies the vagina. The rectum and bladder are likewise located behind the uterus.
These organs can move around freely as there are spaces that separate them. However, if endometriosis occupies these spaces, the organs get glued together. As a result, there is a restriction of movement, which triggers intense pain.
2) During menses or periods, the uterus contracts to throw blood out of the vagina, but because of the confined moment, the organ has to create pressure to push out the blood, causing immense pain.
3) Women also experience a lot of pain during intercourse. As the penis is pushed into the vaginal canal, it comes into contact with the endometriotic tissue, causing discomfort and pain.
4) In cases of deep endometriosis, where the tissue grows around the rectum, women may have discomfort during bowel movements and feel extreme pain while passing stools.
Although many people do not experience any pain despite having deep endometriosis, some feel a lot of pain with very little endometriosis.
The stages of endometriosis and severity of pain may differ from person to person and may fluctuate with time. In addition, endometriosis affects an individual in different ways.
Facts about endometriosis:
- Women under the age of 30 are more likely to be diagnosed with endometriosis.
- 30-40% of women who have infertility suffer from endometriosis.
Normally, many women feel cramps during their periods, but those who have endometriosis report significantly more severe discomfort than usual.

When should you see a doctor?
You may have endometriosis if you have extreme pain during menses, sexual intercourse, or bowel movement. Hence, don’t ignore this sign and immediately consult a specialist.
If you continue to have pain even after the treatment, you might have to see the Endometriosis Doctors as the chance of recurrence is very high with endometriosis.
