Someone suggested I get thermography, where it shows a heat area of infection, or other invasion that raises the temp.

Thermography is a test that uses an infrared camera to detect heat patterns and blood flow in body tissues. Digital infrared thermal imaging (DITI) is the type of thermography that's used to diagnose breast cancer. DITI reveals temperature differences on the surface of the breasts to diagnose breast cancer.Jan 11, 2018
