Constipation for longer than three months with fewer than 3 bowel movements per week, straining, lumpy or hard stools, and a sensation of anorectal obstruction or incomplete defecation.

The presence of chronic diarrhea, which is usually taken to mean diarrhea that has persisted for over 4 weeks.

Idiopathic inflammatory myopathy is a group of disorders characterized by inflammation of the muscles used for movement (skeletal muscles). Idiopathic inflammatory myopathy usually appears in adults between ages 40 and 60 or in children between ages 5 and 15, though it can occur at any age.\n\nThe primary symptom of idiopathic inflammatory myopathy is muscle weakness, which develops gradually over a period of weeks to months or even years. Other symptoms include joint pain and general tiredness (fatigue).\n\nIn sporadic inclusion body myositis, the muscles most affected are those of the wrists and fingers and the front of the thigh. Affected individuals may frequently stumble while walking and find it difficult to grasp items. As in dermatomyositis and polymyositis, swallowing can be difficult.\n\nThere are several forms of idiopathic inflammatory myopathy, including polymyositis, dermatomyositis, and sporadic inclusion body myositis.\n\nPolymyositis and dermatomyositis involve weakness of the muscles closest to the center of the body (proximal muscles), such as the muscles of the hips and thighs, upper arms, and neck. People with these forms of idiopathic inflammatory myopathy may find it difficult to climb stairs, get up from a seated position, or lift items above their head. In some cases, muscle weakness may make swallowing or breathing difficult.\n\nPolymyositis and dermatomyositis have similar symptoms, but dermatomyositis is distinguished by a reddish or purplish rash on the eyelids, elbows, knees, or knuckles. Sometimes, abnormal calcium deposits form hard, painful bumps under the skin (calcinosis).

Enlarged lymph nodes in the neck.

A skin rash that is characterized by diffuse cutaneous erythema with areas of skin elevation. It may evolve to vesicles or papules as part of a more severe clinical entity. Different degrees of angioedema with involvement of subcutaneous tissue may also appear.

A red eruption of the skin.

An increased erythrocyte sedimentation rate (ESR). The ESR is a test that measures the distance that erythrocytes have fallen after one hour in a vertical column of anticoagulated blood under the influence of gravity. The ESR is a nonspecific finding. An elevation may indicate inflammation or may be caused by any condition that elevates fibrinogen.

Extracellular tissue deposition of fibrils that are composed of fragments of and/or intact serum amyloid A protein, a hepatic acute phase reactant.

Periodic (episodic or recurrent) bouts of fever.

Edema affecting the region situated around the orbit of the eye.

Dilatation of the blood vessels of the conjunctiva leading to a red appearance of the sclera.
