Dangerous complications

StrokeThis is an arterial occlusion of the brain vessels. It can lead to speech disorders, impaired vision, disturbances of sensation, motor disorders or headaches. This is also colloquially called a stroke.
Heart attackBy carrying the blood clot from the leg to the coronary arteries, the clot can also block the coronary arteries.
This leads to the classic heart attack. The typical symptoms are chest pain, a feeling of tightness and pressure in the chest. In addition, the pain can radiate into the rest of the chest, into the jaw area, into the upper abdomen or even into the back.

However, there are also unnoticed heart attacks where those affected do not feel any pain at all. This happens especially with diabetics (patients with diabetes) or with older patients. The problem with diabetes (diabetes) is that too much sugar damages the nerves and their signal transmission, so this nerve damage leads to a disturbed perception of pain.

Diabetics, on the other hand, complain of a feeling of pressure in the chest during a heart attack. In addition to the pain, heart rhythm disturbances, a feeling of weakness, fear, nausea, vomiting, sweating or a drop in blood pressure can also occur during a heart attack.
Pulmonary embolismPulmonary embolism is also a blood clot that has spread and is blocking the pulmonary vessels. Here, too, there is pain that starts suddenly, and there is also pain in the chest.
In 90% of the cases, the affected person has acute shortness of breath, an increased heartbeat and breathing rate. In addition, most of them have anxiety and feelings of anxiety, sweating or coughing.

Deep vein thrombosis (phlebotrhombosis) can occur on all levels of the leg. Therefore, thromboses of the popliteal vein are not rare.

Both large deep leg veins and the superficial veins of the lower leg open into this vein. It itself then conducts the venous blood into the femoral vein, a large femoral vein. Thromboses of the popliteal fossa cause corresponding pain in this vein.

In addition, thrombosis in the popliteal fossa usually causes pain in the calf and foot and swelling of these parts of the body, since the venous blood backs up to here. These are also intensified by pressure on the corresponding area. The symptoms typically improve when the leg is elevated, as this promotes the drainage of venous blood from the lower leg.

However, pain in the hollow of the knee does not necessarily indicate a thrombosis. Other causes may be in the musculature and skeletal area, for example. Possible causes include meniscus damage, pulled muscles or biceps tendon tendinosis.
