There are five sensations that could signify a medical emergency.
Sharp pain instead of a dull ache:
This could signal a torn muscle or ligament, as well as a problem with an internal organ in the back or side.
If the discomfort “moves” or “shoots” to the glutes or legs, it could be a sign of nerve compression.
Radiating pain may indicate nerve injury.
Compressed nerves in the spine can induce limb weakness due to disorders such as sciatica or spinal stenosis.
Sudden leg weakness, on the other hand, could signal a stroke.
Back pain combined with inability to regulate bowels or bladder could indicate significant nerve compression or a spinal infection like discitis or meningitis.
Numbness or pins and needles in the groin or glutes:
This is referred to as saddle anesthesia and can indicate a major nerve or spine problem.
If you suffer leg weakness, incontinence, and numbness all at the same time, you may have cauda equina syndrome, a dangerous disorder marked by nerve injury to the spinal cord.
This is a medical emergency, and patients will almost always require rapid surgery to relieve the pressure on the nerves and prevent irreparable harm.
