Hi thanks for your.
You are 84 years completely healthy, all parameters within normal limits, with slight
indigestion and pain right side of abdomen. This indigestion could be due mild gastritis that is inflammation of stomach. Gastritis has many reasons, like spicy food,
cigarette smoking, alcohol, pain killer drugs and infection of stomach by H Pylori bacteria. Most of these don’t hold good for you, but since your pain is on right side radiating to back; it could be due
Gall bladder disease, which could give rise to gastritis leading to, indigestion and pain on right side radiated back.
Take antacid,3 to 4 times a day along with
proton pump inhibitors like pantaperazole 40 mg before breakfast. If you symptoms doesn't settle with this, consult a physician who may get your
ultrasound abdomen done to rule out/confirm any Gall bladder disease responsible for your symptoms.
Hope this answers your question.
