Thanks for your query
The pain described by you seems to me pain to due to costochondritis
. You may have course of non-steroidal anti-inflammatory agents along with pantoprazole
tablets for a week or so. You may take anxiolytics in the form of alprazolam or nitrazepam at bed time to releive your anxiety. Sometimes too much anxiety can give you such feeling. Sometimes mediastinal patholgy may lead to same sort of pain. For this you need to have a chest x-ray followed by contrast chest CT scan. Consult a pulmonologist
and get yourself locally examined. If all the organic causes of your chest pain
have been excluded then consult a psychiatrist
for proper treatment of your anxiety.
