<unk>  is recognized by the presence of pain, warmth, redness, and tenderness over a superficial<unk> . The<unk>  may present as a "cord-like" structure upon palpation. The affected<unk>  may be hard along its entire length.<unk> s tend to involve the legs, though they can affect any superficial<unk>  (e.g. those in the arms). Complications<unk>  in the lower extremities can lead to a dangerous complication in which the clot travels to the lungs, called pulmonary embolism (PE). This is because lower limb<unk> s can migrate from superficial<unk> s into deeper<unk> s. In a French population, the percent of people with<unk> s that also suffered from PEs was 4.7%. In the same population, deep<unk><unk>  (DVT) was found in 24.6% of people with<unk> s. However, because superficial<unk> s lack muscular support, any clots that form are far less likely to be squeezed by muscle contraction, dislodged, and induce a PE.<unk> s can recur after they resolve, which is termed "migratory thrombophlebitis." Migratory thrombophlebitis is a complication that may be due to more serious disorders, such as cancer and other hypercoagulable states.
