Dear sir/ mam, My husband had covid on dated 5 th jan 2022 with a 70% lung involvement.. He took the treatment and now he is covid negative but he have swelling on his hands and legs with heaviness when he sleeps and when he woke up in morning and he is having high coughing too plus he is thyroid and bp patient.. Kindly suggest whether these are the side of covid medication or what!!! . . He feels chest pain sometime.. Thank you!
