Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The overall purpose of the study is to determine how providing physicians with a quantifiable measure of skin surface temperature information influences diagnoses and diagnostic confidence in potential cellulitis cases when added to standard physical exam techniques
The Aims of the study are to :
Specific Aim 1: To characterize the temperature difference between affected and unaffected limbs in patients with cellulitis in the emergency department.
Specific Aim 2: To characterize the temperature difference between cases of cellulitis and pseudocellulitis
Specific Aim 3: To determine how quantifying temperature gradients changes diagnostic confidence and accuracy when added to the standard diagnostic evaluation for potential cellulitis.
The investigators will prospectively enroll a maximum of 560 patients with non-traumatic lower extremity dermatologic complaints with visible erythema (potential cellulitis) in the University of Wisconsin Emergency Department. A thermal image and a photograph of the affected and the unaffected limbs will be taken.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
All Participants
All participants will have thermal imaging of their lower extremities. The temperature values will be shared with the attending physician. The physician will be asked questions about their diagnostic confidence before and after seeing the temperature values.
Thermal Imaging as Diagnostic Adjunct
Thermal images of the participants lower extremities will be taken and skin surface temperature values will be provided to the healthcare provider for review during the emergency department encounter.
Interventions

Thermal Imaging as Diagnostic Adjunct
Thermal images of the participants lower extremities will be taken and skin surface temperature values will be provided to the healthcare provider for review during the emergency department encounter.
