What Causes Severe Back Pain?
Spinal stenosis is a possibility.
Detailed Answer:
Hi, I had gone through your question and understand your concerns.
There are a few conditions that may cause your symptoms and spinal stenosis is a possibility.
Other conditions include degenative vertebral column disease, herniated disc disease, vertebral fracture or lesion etc.
Appropriate diagnosis is achieved by careful clinical and neurological examination correlated to imaging studies and you are scheduled for a scan, so real cause of your symptoms should be clear after imaging.
In mean time I suggest you to wear a lumbar support belt during the day.
Heat procedures on your back, rest should help and combinated pain relieving drugs ( Tramadol + Paracetamol or Codeine +Paracetamol if you are not alergic) should help too in improving symptoms.
Definitive treating modalities should be clear after the correct clinical and imaging diagnosis.
