Thermographic follow-up of postherpetic neuralgia (PHN). Infrared thermograms of lesions and contralateral sides before treatment (A1, A2, A3); one week after the first pulsed radiofrequency (PRF) application (B1, B2, B3); one week after the second PRF application (C1, C2, C3). Infrared thermography showed better performance than contralateral thermography at one week, one month (D1, D2, D3), and three months. Thermographic findings of the pain area showed a higher temperature than that of the the contralateral side at three months when a dose of gabapentin was missed (E1, E2, E3), whereas thermography showed a lower temperature image after gabapentin administration (F1, F2, F3). Scale numbers adjacent to their corresponding colours represent body temperature in degrees Celsius
