Pre-eruptive phase The first signs of<unk>  are often flu-like symptoms such as a fever, cough, malaise, and aching joints. Some people also experience stiffness or swelling in the joints and weight loss. Eruptive stage<unk>  is characterised by nodules (rounded lumps) below the skin surface, usually on the shins. These subcutaneous nodules can appear anywhere on the body, but the most common sites are the shins, arms, thighs, and torso. Each nodule typically disappears after around two weeks, though new ones may continue to form for up to six or eight weeks. A new nodule usually appears red and is hot and firm to the touch. The redness starts to fade and it gradually becomes softer and smaller until it disappears. Each nodule usually heals completely without scarring over the course of about two weeks. Joint pain and inflammation sometimes continue for several weeks or months after the nodules appear. Less common variants of<unk>  include: * Ulcerating forms, seen in Crohn's disease * Erythema contusiforme, when a subcutaneous hemorrhage (bleeding under the skin) occurs with an<unk>  lesion, causing the lesion to look like a contusion (bruise) *<unk>  migrans (also known as subacute nodular migratory panniculitis), a rare form of chronic<unk>  characterized by asymmetrical nodules that are mildly tender and migrate over time.
