It sounds frustrating to have persistent lower back pain despite taking Chymoral Forte and Feldex. Chymoral Forte contains enzymes that help reduce inflammation and swelling, while Feldex is typically used for pain relief and muscle relaxation, but ongoing pain suggests further evaluation is needed.

• Persistent pain on one side of the lower back could be due to muscle strain, nerve irritation, or other underlying issues like a disc problem.
• Since your current medications are not fully relieving the pain, it’s important to see an orthopedic specialist or a spine specialist for a thorough examination.
• They may recommend imaging tests like an X-ray or MRI to identify the exact cause and guide appropriate treatment.
• Meanwhile, avoid heavy lifting or activities that worsen the pain, and consider gentle stretching or heat application if it helps.
• If you experience worsening pain, numbness, weakness, or bladder/bowel changes, seek urgent medical attention.
