• Swelling: The area may appear swollen due to inflammation and fluid accumulation.

Systemic Symptoms

• Skin Changes: The skin over the affected area may become pale, cool to the touch, or exhibit a bluish discoloration (cyanosis).
• Loss of Sensation: Patients may experience numbness or tingling in the arm due to nerve involvement or ischemia.
• Fatigue: General fatigue may accompany the localized symptoms, especially if the ischemia is part of a broader systemic issue.

Patient Characteristics

Demographics

• Age: This condition can occur in adults, particularly those over the age of 50, as vascular diseases become more prevalent with age.
• Gender: There may be a slight male predominance due to higher rates of vascular disease in men.

Risk Factors

• Chronic Conditions: Patients with a history of diabetes, hypertension, or hyperlipidemia are at increased risk.
• Lifestyle Factors: Smoking, obesity, and sedentary lifestyle contribute to vascular health and may predispose individuals to ischemic events.
• Previous Vascular Events: A history of stroke, transient ischemic attacks (TIAs), or peripheral artery disease may indicate a higher risk for muscle infarction.
