Your pain pattern suggests musculoskeletal issue, possibly related to gallbladder or referred pain:
**Differential Diagnosis:**
1. **Gallbladder pain:** Right upper quadrant, radiates to back - fits your description
2. **Gastritis/GERD:** Upper stomach pain, can radiate to chest/back
3. **Musculoskeletal:** Intercostal muscle strain, rib pain
4. **Pancreatitis:** Upper abdominal pain radiating to back
5. **Cardiac:** Less likely in 30yr female but needs exclusion
**Immediate Steps:**
1. Ultrasound abdomen (check gallbladder, pancreas)
2. ECG to rule out cardiac cause
3.
Complete blood count,
liver function tests, lipase
4. Try antacid (pantoprazole 40mg before breakfast)
**Management:**
- Avoid fatty, spicy foods
- Small frequent meals
- Pain relief: paracetamol, antispasmodics (drotaverine)
- If gallstone confirmed, may need surgical consultation
Since Pantoprazole D didn't help, gallbladder pathology more likely than acid reflux. Get ultrasound urgently.
