If one searches under the key word "doctor", a remarkable record comes out. Virtually every day FDR is in Washington from late 1938 to 1945, ther is a record to document a protracted visit to the doctors office. The cover story is that he had been seeing presidential physician Ross McIntire for "sinus" treatment. The reality is likely quite a bit different and related to his panoply of other unadmitted medical problems.
Visits to the hospital clearly documented on laboratory slips are not reflected in the diary. Just another of the many layers of cover-up of the extensive amount of medical treatment FDR received. Treatment that occupied a large and previously unappreciated portion of his life.
Just one page of dozens for your perusal.
