Pain during MenstruationEndometriosis: when severe pain is the norm

During your period you are plagued by excruciating pain that goes far beyond the usual menstrual symptoms? Menstrual cramps limit you in your everyday life and sometimes they are so overwhelming that you can hardly move or work. One cause has not yet been found - you have to cope with the gruelling pain that can extend into your leg and lower back. Month in and month out. But that is not something you really want.

Endometriosis as a cause of severe pain during periods

With endometriosis, cells of the uterine lining - the endometrium - can spread outside the uterine cavity. They can settle on the peritoneum of the pelvis, the ovaries, the bladder or the intestines, sometimes even on the lungs or the kidneys. Since the endometriosis lesions are subject to cyclic hormonal changes, they grow and release chemical substances during menstruation, which trigger pain in the lower abdomen during the period. Until the opposite is proven, lower abdominal pain during menstruation indicates endometriosis. In many women, the pain extends to the leg or the lower back. Sometimes it can even feel like a lumbago or irritation of the sciatic nerve.

Endometriosis of the sciatic nerve

Endometriosis can not only affect the tissues and organs in the pelvic area, the cells can also settle on the sciatic nerve and on any of the nerves in the pelvis. These include the obturatorius nerve, a nerve of the lumbar plexus, and the femoral nerves (thigh nerves). In this form of endometriosis, surgical therapy is necessary to avoid irreversible nerve damage, which leads to motor impairments and particularly affects the lifting and lowering of the foot.

As in the case of endometriosis of the organs, the cell tissue is also removed by laparoscopic surgery if the sciatic nerve is affected. This procedure is the most demanding of all pelvic surgeries and is performed at the Possover International Medical Center by Prof. Possover, using laparoscopy. He is the world's leading expert in this treatment. The use of tiny cameras and fine surgical instruments enables minimally invasive, high precision treatment with the best possible preservation of the nerves.

Endometriosis Center Zurich

An international centre of excellence for advanced procedures

The Endometriosis Center Zürich, under the direction of Prof. Possover offers individual consultation as well as treatments based on the latest medical and scientific expertise. It was evaluated by international experts and was the first centre in Switzerland to be certified as a Level III Endometriosis Centre by the "Endometriosis Research Foundation" and the "European Endometriosis League". This is proof of the high clinical and international scientific level of the physicians working at the Center.

All types of endometriosis are treated, from simple to complex cases. Surgical procedures are almost always performed using laparoscopic surgical techniques. Prof. Possover specializes in laparoscopic surgery of severe endometriosis and is the world's leading expert in laparoscopic treatment of endometriosis of the sciatic nerve.

At the endometriosis centre in Switzerland you will be accompanied and cared for individually - both psychologically and in terms of pain management. The personal needs of our patients and the involvement of their relatives, are just as important to us as the quality of the treatment we provide. It goes without saying that we provide clear explanations and comprehensive information as well as making the right decisions together on care.

Due to the high complexity of the disease, there is close collaboration with other specialists and external services, e.g. when it comes to the wish to have children. In addition, the Endometriosis Center Zurich cooperates with a practice for Traditional Chinese Medicine (TCM) and supplements the surgical and hormonal methods of therapy with complementary medical practices too.
