Right-sided pain can come from many different organs and systems, so it’s not one diagnosis. The right side of your body includes parts of the liver, gallbladder, right kidney, appendix, intestines, and muscles, so causes range from harmless to urgent.
Here are 15 common causes and what they may mean:
🟡 Digestive & abdominal causes
1. Gas and bloating
Very common. Trapped gas in the intestines can cause sharp or crampy right-sided pain.
2. Indigestion
Often causes upper abdominal discomfort after eating.
3. Constipation
Can cause dull or cramp-like pain anywhere in the abdomen, including the right side.
4. Irritable bowel syndrome (IBS)
A functional gut disorder causing recurring abdominal pain and bloating.
🔴 Liver and gallbladder causes
5. Gallstones
Pain in the upper right abdomen, often after fatty meals. Can be severe and sudden.
6. Gallbladder inflammation
Known as Cholecystitis, causes persistent right upper abdominal pain, fever, and nausea.
7. Liver inflammation
Such as hepatitis or fatty liver disease can cause dull right upper discomfort.
🟠 Kidney causes
8. Kidney stones
Sharp, severe pain that may radiate to the back or groin.
9. Kidney infection
Known as Pyelonephritis, often includes fever, pain, and urinary symptoms.
🔵 Appendix-related cause
10. Appendicitis
Starts as vague pain then moves to the lower right abdomen. Medical emergency.
🟣 Musculoskeletal causes
11. Muscle strain
From exercise, lifting, or poor posture.
12. Rib injury or inflammation
Pain worsens with movement or deep breathing.
🟤 Reproductive system causes (if applicable)
13. Ovarian cysts
Can cause one-sided lower abdominal pain.
14. Ovulation pain
Mild, mid-cycle pain on one side.
15. Endometriosis
Chronic pelvic pain that may radiate to the right side.
🚨 When to worry urgently
Seek medical care if pain is:
- Severe or worsening
- With fever, vomiting, or jaundice
- With difficulty urinating or blood in urine
- Sudden and sharp (especially lower right abdomen)
🧠 Key takeaway
Right-sided pain is a location, not a diagnosis. The meaning depends on:
- Upper vs lower right side
- Whether it’s sharp, dull, or crampy
- Associated symptoms (fever, nausea, urinary changes)
If you want, I can help you narrow it down based on exactly where your pain is and what it feels like.
