Rheumatism



Rheumatism is a non-specific term for medical problems afflicting primarily older people, affecting the joints and connective tissue, but normally used to describe any of a number of painful conditions of muscles, tendons, joints, and bones.

Argus Filch suffered from rheumatism, and as such, had trouble when bowing. Horace Slughorn also claimed to do so, but given the agility he featured in his old age, it is unlikely.
