Hi.
Pain in stomach- as you rightly said looks to be due to gastric ulcer. You can start the following:
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.
The light headedness looks to be concerned with your sinus problem as you already have nasal symptoms.
Get a
CT scan , take antihistamine and decongestant nasal drops followed by steam inhalations. This will solve your Problems. You may take an opinion of an ENT Surgeon to confirm the diagnosis and get a proper prescription.
