case_images: Physical examination showed that both ears were mildly red (Figure 1(a) and (b)) with lower temperature (35.2 C for both) than the face (36.2 C) during the interval between the episodes. However, a rapid climbing of stairs for about 5 min led to evident reddening (Figure 1(c) and (d)) associated with marked warmth and pain for both ears, with normal range of heart rate and blood pressure.
