HI.
Thanks for your query.
Since you are not getting a relief with the current medicines , you should go to ER.
Sharp intense pain even on sipping water needs investigations.
I would suggest you to undergo
Upper GI
Endoscopy ASAP
Ultrasonography to start with and confirmatory
CT scan abdomen.
I would advise the following in such a patient:
Continue Zantac 12 hourly.
Pepcid every 3 to 4 hours when on empty stomach.
Add
Domperidone or such motility regulators.
Soft bland diet.
No aerated colas / soda/ drinks.
Early dinner. No late nights.
Treatment for
anxiety (as prescribed / needs a prescription by your Doctor)
Lying in a reclining position
Walk around after dinner.
Think of the factors which increased the present problem, GERD, anxiety and try to avoid.
If no relief, get Upper GI endoscopy done and get prescription for added Medicines.
EKG for the heart n a safer side to rule out cardiac problems.
This helps all my patients and should help you hopefully.
