Brief Answer:
Can be angina(heart related pain).

Detailed Answer:
Hi,
Thanks for query.

There are two pssibilities.
1)Cardiac involvement-Post prandial angina(Pain or discomfort in chest) after eating food in 89 years old male can be suggestive of Angina.Angina means pain due to improper blood supply to heart.Heart is supplied by 3 major vessels called coronaries.Blockage in one of the coronaries can cause angina.

I would strongly suggest him to go for few basic cardiology tests like 2d echocardiogram or Stress echo.They are highly sensitive tests to rule out coronary involvement.

2)Gastric involvement-Gastritis acid disorder and gases can mimic cardiac pain and can cause chest pain and heaviness.
Once cardiac cause is ruled out he can be treated for gastric problem.
Therapy with a proton pump inhibitor like Esomeprazole 40 mg twice daily along with a prokinetic drug would bd given for 21 days. This will provide you symptomatic relief from symptoms.Antacid like tums can be taken for few days along with it.

But as pain is recurrent initially cardiac cause is to be ruled out.

Thank you.

Brief Answer:
Very unlikely.

Detailed Answer:
Hey there,
Going through his symptoms it can't be G.B syndrome.Guillain-Barre syndrome is a rare disorder in which your body's immune system attacks your nerves. Weakness and tingling in your extremities are usually the first symptoms.It is charactrised by ascending umbrella shaped paralysis.Starts from one leg ascends to abdomen and thej reaches the other leg.So an umbrella shaped area is involved.
I respect his opinion but its not G.B syndrome.

Thanks.
