Hi,
Noted your history about having heartburn and also have pain behind neck and left shoulder and feeling like something stuck in throat, happened in past and cardiac check up was normal.
The probable causes can be:
GERD that is gastro-esophageal reflux disease.
Cardiac problems.
Gallbladder disease with or without stones giving
referred pain.
I would advise you the following in such a situation:
Consult your Doctor to find the clinical possibility and get referral for Specialist's opinions and investigations to support.
Upper GI Endoscopy for GERD and
esophagitis related causes.
Ultrasound for gallbladder and liver related problems.
Full Cardiac check up to rule out any heart related problems.
Take a PPI like
Omeprazole.
Relevant tests of blood as would suggested.
All these will give the exact diagnosis so that a specific treatment an be done for permanent relief.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT & General Surgeon
