In many cases, careful management deals with back pain. There is however a species of back pain that  I’ll flag up to you now. The items listed below are “RED FLAG” symptoms which means see your doctor or A & E NOW;  go in and say , “I have back pain symptoms that I think are Red Flag symptoms”

• fever of 38ºC (100.4ºF) or above
• unexplained weight loss
• swelling in the back
• constant back pain from which there is no position of  ease
• Chest pain
• leg pain
•  a change in toilet patterns
• numbness or tingling  around your bottom and privates.
• pain that is worse at night

These are known as ‘red flag symptoms’ and could be a sign of something more serious.
That said, I was checking the NHS  website today (23/7/2020) and it made this  distinction
SEE YOUR GP if

• your painkillers are not helping
• the pain is no better after a month

Go to  A & E or call 999
