When you know the warning signs that need medical attention you can reassure yourself that nothing serious is wrong, even when you have severe back pain. Signs to look out for are:
Bladder or bowel problems
Being unable to pass urine is called urinary retention and is an acute and urgent problem that needs full investigation. It could indicate compression of the cauda equina and you should go to A&E.
Unexplained weight loss and feeling unwell
This could be due to another illness and your back pain may or may not be linked. Go to your GP who can investigate fully.
Night pain
Pain can feel worse at night because you are not distracted with work and chores. This can make you more anxious, but it may simply be due to lying in one position too long and muscle spasm making it difficult to move easily. However, see your GP if your sleep is disturbed and you are unable to lie down because your pain is worse than during the day.
Loss of sensation and weakness in one or both legs
This may indicate irritation or compression of a nerve in the back. It requires assessment to find out how serious the problem is. See your physiotherapist or GP who can assess you and arrange to get you treated appropriately.
Severe leg pain
This may indicate that a nerve root in your back is inflamed or compressed. A physiotherapist can check for weakness, and teach you how to sit more comfortably and specific exercises to help manage the pain. Your GP can prescribe medication to help manage nerve pain and refer you to a physiotherapist.
