Hello!
Thank you for asking on HCM!
Your symptoms could be related to a musculo-skeletal pain or chostochondritis.
Gastro-esophageal reflux or
gastritis can not be excluded either.
For this reason, I would recommend trying an antiacid or PPI (omeprazole,
esomeprazole). If it helps relive your symptoms, it would indicate possible gastritis or gastro-esophageal reflux underlying your symptoms. In such case a fibrogastroscopy would be necessary to confirm the diagnosis.
Otherwise, I recommend trying
ibuprofen. If your symptoms are relied by ibuprofen, it would indicate possible musculo-skeletal pain (including chostochondritis), as the main cause of your complaints.
Anyway, as a cardiologist, I would like to reassure you that your symptoms are not related to the heart, as they are not characteristic of any cardiac disorders.
Hope you will find this answer helpful!
Wishing good health,
Dr. Iliri
