Hello and thank you for join HCM.
Despite the clinical picture i need some more information about your friend as follows:
How old is he?
Does he smoke ,if yes how many cigarettes per day and for how long?
Is he an abuser or drugs, or alcohol?
Where does he work in dirty places?
Does he have any allergies?
It is the first time this sharp pain?
According to the previous information is and the follow up.But in my opinion he should exclude first,cardiac problems than lungs and the last are the problems of the stomach.There are several tests and examinations to do.
EKG
Cardiac Ultrasound
D-Dimmer
Troponin,CK-MB
Chest
X Ray,or a chest CT with i/v contrast
Fibrogastroscopy
According to the results the relevant specialists will advise him for the treatment if it will be needed .
Thank you
Wish you a good health
