Dear patient thank you for your question.
Let me start by saying that you have every right to consult your doctor it would not be bothering him/her because you are his/her's patient.
In my view you either have a severe case of
heartburn brought about by the hernia or a complication known as
esophagitis which is also a complication of the hernia. Your doctor will have to increase the dosage of
lansoprazole but if it doesn't help you may have to go in for surgery of the
hiatus hernia.
i would be remiss if i did not tell you that it could be the following possibilities as well
1) Stomach Ulcer: A ruptured or bleeding ulcer can lead to a similar sirt of pain. An indication of this is if you have pain while eating, constipation/
diarrhoea or black tarry stools
2) Gallstone: Flatulance constipation and
severe pain on breathing may point towards gallstone. A simple usg bladder will rule it out.
3)Pancreatitis: Severe pain RADIATING to the back which is relieved on crouching forward. A pancreatic profile and cat scan should rule it out.
I would like to
stress again that you should definitely contact your doctor and discuss the above mentioned possibilities as hiatus hernia is no small thing.
i hope this helped
