Having the symptoms you are presenting could lead to a variety of diagnosis such as idiopathic pleuritic chest pain
, pneumopathy (pneumonia
, neoplasia etc), heart condition etc
You were probably sent to the gastroenterologist because they were probably suspecting gastritis
( which i don't think is the case because of the locations of your pains). You will start by doing a chest x-ray ( some chest affections might present without cough or other signs of respiratory affection like difficulty breathing
, rapid respiration etc).
By doing a chest x-ray or CT scan or MRI we could be able to tell if there is a lung lesion.
To alleviate your symptoms you can be placed on oral steroidal anti-inflammatory before further investigations are done.
Hope this helps
