Hello
Welcome to health care magic
I would like to ask you certain questions as information provided is inadequate,
-Has he had all these symptoms ever before?
-Has he experienced sleep and appetite changes recently?
It looks out to be anxiety disorder/
mood disorder.
If the symptoms are affecting his routine activities and relations or if these symptoms are present for more than 3 weeks,you need to visit
psychiatrist.
Detailed medical history is important for diagnosis.
Behaviour therapy will be needed under consultation of
psychologist.
Breathing exercises and meditation will help in long run.
Avoid alcohol,smoking or any other
substance abuse.
You need to understand him and talk about his problems.
Hope I answered your query.
Wish him good health.
