Pain or tenderness in the legs is not a normal condition. One of the most common causes of pain in the lower extremity is venous insufficiency, a condition in which the veins stretch over time and the one-way valves in the veins fail. This valve failure allows venous blood to flow down the leg due to the effect of gravity. This downward flow of blood causes high pressures to develop in the leg veins. This high pressure (chronic venous hypertension) causes stretching in the vein walls which may cause pain. An inflammatory condition will develop over time around the veins resulting in pain and/or tenderness in the soft tissues of the leg.
Pain or tenderness in legs may also be the result of clotting (thrombosis) in the veins. Superficial thrombophlebitis refers to clotting and inflammatory changes in the veins of the skin and fatty tissues. Deep vein thrombosis refers to clotting in veins inside the muscles of the leg. Untreated venous thrombosis may worsen and result in more pain, destruction of valves in the veins, or a clot which migrates (embolizes) to the lungs (pulmonary embolism).
Some of the other causes of leg pain include bone or joint disorders, low back problems, such as arthritis or disc degeneration with compression of nerves, neuropathy, infection, arterial insufficiency (blockage of arteries carrying blood to the legs), or trauma. Leg pain from venous insufficiency is often misdiagnosed as Fibromyalgia.
Too often, patients with soft tissue pain or tenderness in the legs are misdiagnosed if they do not have large, obvious, varicose veins. They may be sent for a venous ultrasound exam at a laboratory which tests only for venous thrombus (clot) and ultrasound testing for venous insufficiency is not performed. A “normal” report after testing only for venous thrombus will miss the diagnosis of venous insufficiency.
If you have soft tissue pain or tenderness of the lower extremities, be sure to get a complete diagnostic venous color duplex ultrasound exam, including testing for venous insufficiency. This is a specialized exam which is best performed in a center dedicated to the evaluation of venous diseases.
