This thermogram shows an obvious hypothermia (cold) of the entire left arm. This patient had been experiencing chronic tingling and numbness. He had been diagnosed with a cervical spine neuropathy and had been undergoing physical therapy on and off with only mild temporary relief. The thermal findings were suggestive of a neurovascular problem likely arising from the thoracic outlet and not a cervical neuropathy. Upon further testing it was confirmed that the patient had thoracic outlet syndrome. With this new diagnosis the patient was able to get proper care.
