Regular waist pain often stems from poor posture, muscle weakness, or spinal wear, which topical pain-relief gels only temporarily soothe. For a long-term solution, relying indefinitely on medication is not recommended. Instead, a permanent cure usually involves physical therapy. I highly recommend consulting a physiotherapist to learn core-strengthening exercises and posture correction. For temporary flare-ups, generic oral anti-inflammatories like ibuprofen or paracetamol can be used under medical supervision. Please consult an orthopedic specialist or doctor for an evaluation (and imaging if needed) to diagnose the exact cause and guide your long-term recovery safely.

Since the topical spray isn't helping, the best immediate home remedy is the PRICE protocol: Rest the shoulder, apply Ice packs for 15-20 minutes several times a day, use a supportive wrap for Compression, and keep it Elevated. Over-the-counter generic relievers like ibuprofen or paracetamol can also reduce discomfort. Regarding exercise, please avoid strenuous workouts or lifting weights with the injured arm right now, as this can worsen the injury. Rest is crucial for healing. You should only transition to gentle, pain-free stretching once the acute pain has subsided. If the pain persists or worsens, please consult a doctor for a physical assessment.

This sounds like a muscle strain in the lower back. Along with Volini and the capsicum band, she should rest her back, avoid bending or lifting, and use warm compresses 2 to 3 times a day. Gentle stretching can be started once the pain reduces. If the pain is severe or not improving in a few days, she should see a doctor for further evaluation.
