Hi,
Thank you for posting your query.
He seems to have had
sinus infection, which was adequately treated by his GP.
In addition, his shakiness could be essential tremors, as there is no slowness or rigidity of
limbs to suggest a diagnosis of Parkinson's disease. These tremors would improve with beta blockers.
I hope my answer helps. Please get back if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
