Both come up when a sore throat, swollen gland or spot is coming to a head with pus.

From the classic texts
“Chilliness, hypersensitiveness, splinter-like pains, craving for sour and strong things are very characteristic. Feeling as if wind were blowing on some part.”
“A human "thermometer". Sensitive to heat and cold. Parts are much swollen, with raw, sore feeling; the profuse, oily perspiration does not relieve.”
