[28F] Experiencing abdominal pain, vomiting, and rash

What might be happening

Based on the information you've provided, possible diagnoses include:

• Gastroenteritis: This is an inflammation of the digestive tract, often caused by a viral or bacterial infection. Symptoms can include stomach pain, vomiting, and a rash. However, gastroenteritis usually resolves within a few days to a week, and your symptoms have been ongoing for a few weeks.

  • Treatment typically involves rest, hydration, and over-the-counter remedies. If symptoms persist, a doctor may prescribe medication.

• Gastritis or Peptic Ulcer Disease: These conditions involve inflammation or erosion of the stomach lining, which can cause pain and vomiting. Gastritis can be caused by long-term use of NSAIDs, excessive alcohol, stress, or certain bacteria. Peptic ulcers are often caused by the same bacteria or by long-term use of NSAIDs.

  • Treatment usually involves medications to decrease stomach acid and possibly antibiotics to treat any bacterial infection.

• Gallstones or Biliary Disease: Even though you've had your gallbladder removed, it's possible to still have issues with your bile ducts, which can cause pain in the upper right abdomen and vomiting.

  • Treatment may involve medication or, in some cases, surgery.

• Pancreatitis: Inflammation of the pancreas can cause upper abdominal pain that radiates to the back, along with nausea and vomiting. However, this is usually associated with heavy alcohol use or gallstones, neither of which you've reported.

  • Treatment usually involves hospitalization for pain management and treatment of the underlying cause.

The rash you're experiencing could be related to your other symptoms if there's an underlying systemic cause, but it could also be unrelated. It could be due to a variety of causes, such as an allergic reaction, a viral infection, or a dermatological condition.

What you can do

Given the severity and duration of your symptoms, it's important that you seek medical attention as soon as possible. A healthcare professional will be able to evaluate your symptoms, perform any necessary tests, and provide appropriate treatment.

In the meantime, try to stay hydrated, especially since you're experiencing vomiting. Water, broth, or rehydration solutions can be helpful. Avoid any foods that seem to worsen your symptoms.

What you should look out for

Seek immediate medical attention if you experience any of the following:

• Severe abdominal pain
• Blood in your vomit or stool
• High fever (over 101°F)
• Signs of dehydration, such as dry mouth, not urinating, or feeling extremely thirsty or lightheaded
• Difficulty breathing
