Brief Answer:
PPI's are the main stay of therapy

Detailed Answer:
HI Sir,

Gastritis in your case(drug induced gastritis likely ) can be effectively managed with acid suppressing drugs(Proton pump inhibitors) like pantoprazole and rabeprazole.

These drugs should be taken once a day before breakfast at 7 am.

These drugs should be taken for 21 continuous days.

Aspirin is known to cause severe gastritis on long term use.

Drug called clopidogrel can be substituted for aspirin.

I strongly recommend you to have an upper gastrointestinal endoscopy along with mucosal specimen for rapid urease test.

This test can accurately predict the coexistence of H pylori,an acute gastritis causing organism.

In such cases a 4 week therapy with anti pylori antibiotics will offer cure.
encourage yourself for cessation of smoking and alcohol if any.

Cold milk at bed time can provide alkaline environment.

Elevate head end of bed by 30 degrees.

I hope this info is helpful to you
Thank you

Brief Answer:
sinusitis can definitely lead to headache

Detailed Answer:
HI,

There is extremely good chance of calcified superior being the source of your headaches.

Hypertrophied/inflammed superior turbinate can block the free flow of fluid across the meatusus leading to frontoethmoidal sinusitis.

Cacified turbinate can impinge on to the nerve leading to recurrent headaches.

Sinusitis can lead to positional variations of inflammed fluid that can contribute to headache free periods.

Thank you
