Hi welcome to health care magic forum,
Wysolone is a prednisolone
used for allergic maxillary nasal polyposis.
Its side effect may cause increase in appetite with acid peptic disease
which may present with lower chest pain
and abdomen pain.
Heaviness and tiredness
throughout day is less likely to be of it side effect.
I would like to suggest you to take food in time, plenty of water and antireflux agent like pantoprazole
or rabiprazole for 3 to 4 days .
But if no relief than you must do a ECG and see a medicine specialist or a cardiologist for proper evaluation and to exclude any other associated disorder.
