You should seek medical help if you experience any tingling sensation and/or if you have back pain:
- that does not improve with rest
- after an injury, such as after a car accident
- with numbness in the legs
- with weakness
- with fever
- with unexplained or unintentional weight loss
- with loss of bladder or bowel control
- that is so bad you’re having problems sleeping
- that is worse when sneezing, coughing
The above may be a sign of something more serious and need to be checked urgently. https://www.nhs.uk/conditions/back-pain/#:~:text=When%20to%20get%20immediate%20medical,control%20%E2%80%93%20peeing%20or%20pooing%20yourself
