Dr Joseph Kamugisha Swelling of the lower limbs (edema) is a common clinical complaint in our daily practice. Many people suffer problems of inexplicable swelling of legs with no history of illness. This could be an indication of circulation problem. One should know how you can improve your blood circulation in case you suffer from this problem. In medical practice, we tend to prescribe medications that aid the body to eliminate fluid in the body to patients with swollen limbs. Strong and steady blood flow allows for constant exchange of nutrients and waste at the cellular level, and promotes healthy flow of fluid through the lymphatic system, a key component of the immune system. Being active and minimising intake of refined carbohydrates and damaged fats are arguably the most important requirements for healthy blood circulation. A simple and powerful way of promoting strong and steady blood circulation throughout the legs is to massage the soft depression found at the back of the knees. This area is called the popliteal fossa, and contains blood vessels, nerves, and even components of the lymphatic system. By gently massaging the region, you can promote healthy blood flow and nerve tone in the lower extremities. A powerful acupuncture point is located right in your popliteal fossa and represent clusters of major blood vessels and nerves. You can locate the popliteal fossa by feeling the underside of your knee while seated and your knees are bent at 90 degrees. Toward the thigh side of your popliteal fossa, you should feel tendons of hamstring muscles on both sides. Toward the calf of your popliteal fossa, you should feel the inner and outer heads of your upper calf muscle. Located within your popliteal fossa are several lymph nodes and lymphatic vessels. Popliteal artery, which is a continuation of your femoral artery these two arteries deliver blood to your entire lower limb. It’s always prudent to check with the doctor before one begins any programme of self care, including pressure work in the popliteal fossa. If you take it slow and listen to the body’s response to massage of the popliteal region, you can almost certainly stand to experience improved blood flow, nerve tone, and overall health in the lower limbs.
