Thank you for posting your query.
I have noted your symptoms and it is unlikely that they are related to a single cortisone injection
in the knee.
The onset of these symptoms after the injection is most likely coincidental.
I request you to consult your GP and get evaluated for these symptoms. We need to check thyroid
profile, do cardiac work up, etc.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
