Hi Ms Swathi,
Thank you for posting your query.
I have noted your father's medical details. I am glad to note that he has withstood two brain surgeries well.
The recent
fever may or may not be related to the surgery. Please get him examined by the neurosurgeon to look for any infection at the operation site. If that is ruled out, then, we should look for other sources of infection such as
pneumonia or
urinary tract infection.
I am sure he would improve with
physiotherapy and appropriate medical treatment.
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,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
