Kept my bed most of the day + felt easier. It was a nicer day than yesterday. Yesterday on the way back from Cheviot I was seized with cramp in my left Sartorius1 which gave me most excruciating pain for a short time.
1 See Dr Muir’s diary entries for 23 and 24 August 1922; the sartorius muscle is a thin, long, superficial muscle in the anterior compartment of the thigh [source: Moore, Keith L; Dalley, Arthur F; Agur, A M R (2013). ‘Clinically Oriented Anatomy’. Lippincott Williams & Wilkins. pp. 545–546].
