There are several reasons for the pressure pain in the lower right abdomen of women: first, it may be due to inflammation, in clinical terms the small abdomen usually refers to the female pelvis, which houses the uterus, ovaries, fallopian tubes and other reproductive organs. When there is inflammation in some of these organs, there will be exudative hyperplasia as well as ulceration and cell necrosis on the surface of the skin mucosa of the organ. There will also be vascular hyperplasia and there can be increased vascular permeability and also exudation of inflammatory material. All these factors can stimulate the sensory nerves on the skin and mucous membrane of the organ, and when women press these parts with their hands, it will cause pain due to the stimulation of the nerves. Secondly, it is necessary to consider whether there is tumor growth, such as fallopian tube tumor, ovarian tumor, retroperitoneal tumor, broad ligament myoma and so on. When there is a tumor growing in the small abdomen, women will have some pressure and squeeze on it when they press it with their hands, which will also produce painful sensation. Thirdly, because the appendix is also located in the right lower abdomen, so the possibility of appendicitis should also be considered.
