Here is a thorough breakdown of what you are experiencing:

Postprandial (After-Eating) Abdominal Pain + Abdominal Hardness

What "Hard on Palpation" Means

When your abdomen feels hard or tight when you press on it, this is called abdominal guarding or rigidity. According to Bailey and Love's Short Practice of Surgery (28th Ed., p. 1077), this happens when the abdominal wall muscles contract — either as a reflex response to underlying inflammation or irritation. The muscles tighten to "protect" the area underneath. Mild guarding usually points to a localized problem (stomach, intestines, or nearby organs) rather than a surgical emergency.

Most Likely Causes for Your Symptoms

Given that your pain comes specifically after eating rice + vegetables/chicken, here are the most probable reasons, from most to least common:

1. Indigestion / Functional Dyspepsia (Most Common)

  • Pain or discomfort in the upper-middle abdomen after meals
  • Bloating, feeling of fullness, mild cramping
  • Triggered by heavy, spicy, or oily foods
  • The abdomen can feel tense/hard due to gas and bloating distending the gut

2. Gastritis (Stomach Inflammation)

  • Inflammation of the stomach lining caused by H. pylori infection, excess acid, or spicy/oily food
  • Pain typically in the upper abdomen (epigastric area), worsens after eating
  • Very common in South Asian diets with spiced foods

3. Irritable Bowel Syndrome (IBS)

  • Crampy abdominal pain after meals, often with bloating, constipation, or loose stools
  • Abdomen can feel tense and hard due to trapped gas and bowel spasm

4. Constipation

  • If your bowel movements have reduced or stools are hard, the colon can fill up and feel hard to the touch
  • Pain and bloating worsen after eating because eating triggers gut movement

5. Peptic Ulcer Disease

  • Ulcers in the stomach or duodenum
  • Pain can worsen right after eating (gastric ulcer) or improve briefly then return
  • More common with irregular eating habits or H. pylori infection

6. Non-Vegetarian Food Intolerance / Poor Digestion

  • Chicken and other proteins take longer to digest; if stomach acid is low or digestion is sluggish, they can cause cramping, heaviness, and bloating

7. Chronic Mesenteric Ischemia (Less Common, Worth Knowing)

  • Per retrieved sources, this causes crampy mid-abdominal pain within 30 minutes after eating, sometimes lasting hours. This is due to reduced blood flow to the intestines — less likely in younger individuals but worth mentioning.

Warning Signs — See a Doctor Promptly if You Have:

SymptomWhy It Matters
Severe or worsening painCould indicate ulcer, appendicitis, or obstruction
Board-like rigid abdomenSign of peritonitis — a medical emergency
Vomiting blood or dark/tarry stoolsSuggests GI bleeding
Unintentional weight lossNeeds urgent investigation
Fever with abdominal painSuggests infection or abscess
Pain at rest (not just after eating)More serious pathology

What You Should Do

  1. Track your symptoms — note which foods trigger pain, how soon after eating, and where exactly the pain is (upper abdomen, around belly button, lower abdomen, one side)
  2. Avoid trigger foods temporarily — very oily, spicy food; try bland, light meals for a few days
  3. Don't skip meals — irregular eating worsens gastritis and acid-related problems
  4. Visit a doctor — since this has been going on for several days, a physical exam and basic tests (H. pylori test, ultrasound, blood work) are recommended to rule out gastritis, ulcers, or other causes
The combination of recurring post-meal pain + abdominal hardness lasting for several days should not be ignored. A gastroenterologist or general physician can examine you properly and may order an abdominal ultrasound or upper GI endoscopy if needed.

I have pain only in upper side like in costal arch area

This is very helpful — pain specifically in the costal arch area (under the ribcage) after eating narrows things down significantly.

Pain Along the Costal Arch After Eating

The costal arch runs along the lower border of your ribcage. Pain here after eating points to specific organs sitting just under that area:

Based on Which Side:

Right Side (Right Hypochondrium / Under Right Ribs)

This is the most clinically significant location. The main organs here are the gallbladder, liver, and the beginning of the large intestine (hepatic flexure).
ConditionKey Features
Gallstones / Biliary Colic (Most Likely)Pain under right ribs after eating fatty/oily food (chicken, fried items). Pain can radiate to right shoulder blade. Comes in waves. Nausea common.
Cholecystitis (gallbladder inflammation)Similar to above but pain is more persistent, may have fever. Tenderness under right ribs on pressing.
Liver-related painDull ache or heaviness under right ribs. Caused by liver enlargement, fatty liver, or hepatitis. Per Harrison's (p. 9303), arises from stretching of Glisson's capsule surrounding the liver.
Hepatic flexure syndromeTrapped gas at the bend of the colon under the right ribs — causes sharp pain after eating, relieved by passing gas/stool.

Left Side (Left Hypochondrium / Under Left Ribs)

ConditionKey Features
Gastritis / Peptic UlcerBurning or gnawing pain in upper-left/central area after eating. Common with H. pylori or spicy food.
Splenic flexure syndromeTrapped gas at the left bend of the colon — pain under left ribs, bloating, relieved by passing gas.
SplenomegalyEnlarged spleen causes fullness and dull pain under left ribs.

Central (Epigastric / Both Sides)

  • Functional Dyspepsia — Per Harrison's (p. 8917), this is the most common cause of upper abdominal discomfort. Symptoms include postprandial fullness, early satiety, and epigastric burning. Up to 30% of people experience this.
  • GERD (Acid Reflux) — Burning sensation rising from upper abdomen after meals.

The Hardness You Feel

When you press on the costal arch area and it feels hard, this can be:
  • Muscle guarding — your abdominal muscles tensing reflexively to protect an irritated organ underneath
  • An enlarged organ — a tender, enlarged gallbladder or liver edge can feel firm/hard just under the ribs
  • Gas-distended colon — the hepatic or splenic flexure filled with gas feels hard to touch

Most Probable Diagnosis Given Your Description

Gallbladder issue (gallstones or gallbladder inflammation) is the top suspect because:
  • Pain is specifically under the costal arch (right side, typically)
  • Triggered by meals — especially after chicken or oily/fatty food
  • Area feels hard/tender on pressing
  • Ongoing for several days
Fatty liver or hepatitis is also worth ruling out if you have a diet high in rice, oil, and meat regularly.

What to Do Next

  1. Tell your doctor exactly where the pain is — right side, left side, or both sides under the ribs
  2. Get an abdominal ultrasound — this is the single most useful first test. It can detect gallstones, gallbladder inflammation, liver enlargement, and fatty liver easily and cheaply
  3. Blood tests — liver function tests (LFT), CBC, and if suspected, H. pylori testing
  4. Avoid fatty/oily meals until you get checked — this reduces stress on the gallbladder
Do not delay if you develop fever, yellowing of eyes/skin (jaundice), vomiting, or severe pain — those would need urgent care.

I have pain only in costal arch area and pain is usually after 10 to 20 minutes after eating and lasts about an hour or more but mot for much time and the pain is mild everything else in normal no fever no problem in stools or anything just a mild pain after 10 minutes of eating not radiating

Based on your very specific pattern — pain only in the costal arch area, starting 10-20 minutes after eating, lasting an hour or so, mild, no radiation, no fever, no stool changes — this picture is quite clear.

Your Symptom Pattern Points To:

1. Functional Dyspepsia (Most Likely)

This is the single most common cause of exactly what you are describing. Per Harrison's Principles of Internal Medicine (p. 1226 & p. 8917):
  • It is upper abdominal pain/discomfort triggered by meals, with no ulcer or structural disease found
  • It has two subtypes — yours fits Epigastric Pain Syndrome (EPS): pain or burning in the upper abdomen that is meal-related
  • Affects up to 30% of the general population
  • H. pylori infection is a known contributing factor
  • Most cases follow a benign course

2. Gastritis (Close Second)

  • Inflammation of the stomach lining, very commonly caused by H. pylori or irregular eating habits
  • Pain begins shortly after food hits the stomach (10-30 min), exactly matching your timeline
  • Mild, dull, or burning ache in the upper abdomen / under the ribs
  • No alarm features — consistent with mild/early gastritis

3. Peptic Ulcer (Less Likely but Possible)

  • A gastric ulcer causes pain soon after eating (when food stimulates acid), while a duodenal ulcer usually causes pain when the stomach is empty
  • Your timing (10-20 min after eating) fits a gastric ulcer pattern more
  • However, the absence of severe pain, vomiting, or blood in stool makes a simple ulcer without complications more likely if this is the cause

Why the Costal Arch Feels Hard

With gastritis or dyspepsia, after eating:
  • The stomach fills with food and gas
  • Acid secretion increases
  • The stomach wall and surrounding muscles can go into mild spasm
  • This causes the upper abdominal wall just below the ribs to feel tense and firm when pressed — it is not a hard organ, it is muscle tension from the irritated stomach underneath

What You Should Do

Simple steps first:
  1. Eat smaller meals — large meals overfill the stomach and worsen dyspepsia/gastritis
  2. Avoid skipping meals — an empty stomach increases acid, which irritates the lining
  3. Reduce spicy, oily, and acidic foods temporarily
  4. Avoid lying down right after eating — wait at least 30-45 minutes
  5. Reduce tea/coffee on an empty stomach if you do that
See a doctor for:
  • A test for H. pylori (breath test or stool antigen test — simple and cheap)
  • If positive, a short course of triple therapy antibiotics + antacid cures it
  • Short course of a PPI (proton pump inhibitor) like omeprazole can relieve symptoms within days
  • Upper GI endoscopy only if symptoms persist despite treatment or worsen
Since this has been going on for a few days and is mild with no alarm signs, it is not urgent — but getting a doctor's opinion within the next week or two is a good idea to confirm and treat properly.
