40/100Rarity: uncommon
TechnicalRegister
A temporary worsening of symptoms, particularly pain, after a period of relative stability.
A flare-up after gardening is normal and doesn't mean you've caused any damage, so we'll just ease back the exercises for a few days.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
