[47F] Experiencing sudden, sharp lower abdominal pain and swollen groin lymph node

What might be happening

Based on the information you provided, the following conditions could be causing your symptoms:

• Appendicitis: This is an inflammation of the appendix, a small pouch attached to the large intestine. It typically causes severe pain in the lower right abdomen, but can sometimes cause pain around the belly button or on the left side if the appendix is located there. The pain is usually sudden and severe, and can be accompanied by tenderness in the area, fever, and chills.

  • Treatment usually involves surgery to remove the appendix.

• Kidney stones: These are hard deposits made of minerals and salts that form inside your kidneys. Pain can be severe and usually starts in the back or side below the ribs, and can radiate to the lower abdomen and groin. The pain may come in waves and fluctuate in intensity.

  • Treatment can involve pain relief, drinking lots of fluids to help pass the stone, or medical procedures to remove or break up larger stones.

• Ovarian cyst: This is a fluid-filled sac that forms on or inside an ovary. Most ovarian cysts are harmless and go away without treatment in a few months. However, ovarian cysts can cause a variety of symptoms, including pain in the lower abdomen, bloating, and tenderness in the area.

  • Treatment can involve monitoring the cyst, birth control pills to prevent new cysts from forming, or surgery to remove the cyst.

• Diverticulitis: This is an inflammation or infection of small pouches called diverticula that develop along the walls of the intestines. The formation of these pouches is known as diverticulosis. Diverticulitis can cause severe abdominal pain, fever, and chills.

  • Treatment can involve antibiotics, a liquid diet to allow the colon to heal, or surgery in severe cases.

What you can do

Given the severity of your symptoms, it is important to seek immediate medical attention. While waiting for medical help, try to rest and avoid eating or drinking in case you need surgery.

What you should look out for

Watch out for worsening symptoms, such as:

• Increasing pain or pain that becomes constant
• High fever (temperature over 100.4°F)
• Nausea and vomiting
• Blood in your stool or urine
