I'm sorry to hear that your lower left abdominal pain is returning despite the initial treatment. The medications you mentioned—Flagyl (metronidazole), Vibramycin (doxycycline), and Histac (likely an acid reducer)—are often used to treat infections and related symptoms. The addition of Secnil Forte (which appears to be an antibiotic tablet) suggests your doctor is adjusting your treatment to better target the cause of your pain.

Important points to consider:

• Persistent or returning abdominal pain after initial antibiotic treatment may indicate that the infection or underlying cause has not fully resolved.
• It is essential to follow your doctor's instructions carefully with the new medication.
• If the pain worsens, is severe, or is accompanied by other symptoms such as fever, vomiting, or changes in bowel habits, seek medical attention promptly.
• Further evaluation, including imaging or lab tests, might be necessary to identify the exact cause of your symptoms.

Recommendation:
Please continue the prescribed course of Secnil Forte as directed and schedule a follow-up appointment with your doctor or a gastroenterologist to reassess your condition. If you experience severe pain, fever, or other concerning symptoms, do not hesitate to seek emergency care.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
