Why routine imaging often makes things worse, and which red flags — saddle numbness, bladder changes, progressive leg weakness — need an emergency department.

Numbness & Tingling: When Pins-and-Needles Is a Warning — A foot that falls asleep is normal; recurrent tingling in the same fingers isn't. The pattern of where, when and how long tells you whether to shrug it off or seek care.
