It is understandable to be concerned about persistent lower abdominal pain, especially when it affects your daily activities. Since your sonography is normal and doctors have identified the pain as muscular, it likely relates to muscle strain from your previous brisk walking routine.

🩺 Managing Muscular Pain

• Rest and avoid activities that worsen the pain, such as brisk walking, until symptoms improve.
• Apply warm compresses to relax the muscles and reduce discomfort.
• Gentle stretching and mild exercises may help once acute pain subsides, but start slowly.
• Over-the-counter pain relievers or prescribed muscle relaxants like Thioquest DP (a combination of diclofenac, paracetamol, and thiocolchicoside) can reduce pain and muscle spasm; however, use them only under your doctor’s guidance.
• Maintain good posture and avoid prolonged sitting or standing in one position.

⚠️ When to Seek Further Medical Advice

• If pain worsens, spreads, or is accompanied by fever, vomiting, or urinary symptoms.
• If pain persists beyond a few more weeks despite conservative care.
• If you notice any new symptoms like swelling, redness, or numbness.

Since your pain has lasted three months, it is important to follow up with a specialist such as a physiatrist (physical medicine and rehabilitation doctor) or an orthopedic specialist for further evaluation and tailored treatment. They may recommend physical therapy or additional investigations if needed.
