Hello, The issue of radiating pain from upper back to mid abdomen which exacerbates with nose blowing indicates most likely paraspinal muscle stretching in form of sprain or strain. My guidelines for better recovery: - Local application of heating pad - Use to spray or apply ointment containing Diclofenac, Linseed oil, Capsaicin with or without Menthol with gentle rubbing over the affected sore part of back - Analgesic and anti-inflammatory medications such as Ibuprofen, Diclofenac or Etoricoxib - Muscle relaxant as Chlordiazepoxide or Tizanidine may be indicated in selected cases of severe spasm - Avoid sudden bending or weight lifting - Avoid certain postural adaptations which may worsen the condition - Assisted physiotherapy has role in some issues Remain in regular follow up with your primary care provider till complete recovery. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Bhagyesh V. Patel, General Surgeon
