If you often experience leg cramps or a numb/“not-my-own” sensation in part of your foot without any recent injury, the true source may be your lumbar spine rather than the leg itself. At MADI-BONE CLINIC near Seolleung Station, Gangnam, we specialise in finding and treating spine-related leg symptoms.

“I didn’t overdo anything… but my left leg keeps cramping and my foot feels strange.”

A recent patient told us exactly this: there was no recent strain or trauma, yet she had frequent muscle cramps in the left leg and felt that a part of her sole was unfamiliar, almost “not my own foot.” After listening to the full story, the pattern pointed to the lower back as the likely origin.

Why a Lower Back Problem Can Show Up as Leg Symptoms

Nerves exiting the lumbar spine travel down into the leg, foot and toes. When a nerve is compressed—by a disc herniation, spinal stenosis, thickened ligaments or hypertrophic facet joints—patients may notice:

  • Cramping or involuntary muscle tightening in the leg
  • Numbness or altered sensation in part of the foot
  • Tingling or burning following a dermatomal (nerve) pattern

In other words, symptoms that feel like a leg problem can actually originate from the spine.

Treat the Root Cause—So the Leg Improves

At MADI-BONE CLINIC, we combine X-ray, ultrasound and C-arm fluoroscopy to localise the compressed nerve at its exit or within the spinal canal. With targeted epidural or selective nerve-root injections we aim to:

  1. Reduce inflammation and swelling around the affected nerve
  2. Create more space in the narrowed canal/foramen
  3. Relieve leg cramps, numbness and tingling more effectively than “leg-only” care

Many initially-skeptical patients respond quickly and often say, “I can’t believe my leg symptoms improved after a back treatment!”

Pain and Cramps Are Signals—Don’t Ignore Them

Persistent, unexplained cramps or numbness should never be dismissed. Untreated nerve compression can lead to chronic changes and prolonged neurological impairment. Early diagnosis and targeted treatment generally produce better outcomes.
