3) Diseases of muscles, tendons and the hip joint

Abscesses on the right, left or both sides belong to the rather rare diseases that lead to groin pain. Especially the so-called “subsidence abscess in the pelvis” (psoas abscess) plays a decisive role in this context. An abscess is usually caused by purulent meltdown within an inflamed tissue section.

In the pelvis, abscesses typically spread along the lumbar iliac muscle (psoas muscle) to the groin. In addition, aneurysms of the femoral artery can cause groin pain on the right or left side. In the case of an aneurysm, either the entire wall of the vessel bulges outwards or only a few layers of the wall.

The wall of the vessel becomes thinner at this point and may rupture. Often the descending abscess is caused by a bacterial infection of the lumbar spine, a purulent hip prosthesis or the intestine. A descensus abscess can occur on the right or left side as well as on both sides.

The main cause for the development of an aneurysm of the femoral artery is vascular calcification (arteriosclerosis). Patients who have a descending abscess often notice local protrusions in the groin area. In addition, the abscess typically severely restricts hip mobility.

Especially in the early stages, there is usually no groin pain, since the pressure increase within the tissue is still relatively low. However, as the stage progresses, this pressure increases and causes severe groin pain in the affected patients. In addition, groin pain is one of the typical symptoms of a thigh aneurysm.

Patients suffering from a thigh artery aneurysm often notice a pulsating tumor that can increase in size. A direct consequence of the progressive vascular sacculation can be a circulatory disorder of the lower extremity. Depending on the location of the aneurysm, signs of oxygen deficiency appear either on the left or right (very rarely on both sides).

The most important signs in this context are white/blue discoloration of the skin, pain and sensation. The most serious complication of such a descensus abscess is the spontaneous opening towards the inside of the body. If the abscess cavity bursts open uncontrolled, the causative bacteria can enter the bloodstream.

In this case there is a risk of life-threatening blood poisoning (sepsis). The descending abscess is typically surgically opened and cleared. In addition, the affected patient must take an antibiotic to prevent possible complications.

The most common cause of groin pain during pregnancy is the so-called “pelvic ring loosening”. Pelvic ring loosening” is a stretching of the ligaments that hold the individual pelvic bones together. This stretching can occur in the early stages of pregnancy or be triggered by the birth process.

For the actual birth process, however, pelvic ring loosening is essential. Typical symptoms of this process are groin pain and complaints in the area of the loins, the spine and the pubic bone. Due to the enormous stretching of the ligaments, walking and overall mobility can be severely restricted.

Incorrect posture during pregnancy can promote the symptoms typical of pelvic ring loosening. Although groin pain during pregnancy is not uncommon, the complaints should not be accepted as such. Physical relief can help to relieve the groin pain and increase the well-being of the expectant mother.
