Progressive relapsing multiple sclerosis

Progressive relapsing multiple sclerosis (MS) is a rare form of MS that causes steady damage to nerves when symptoms first appear and continues to cause progressive worsening. Relapses (disease flare-ups) occur, followed by full or partial recovery, but nerve damage continues and symptoms become increasingly disabling.

Symptoms of MS include:

  • Weakness, leg dragging, and stiffness.
  • Blurred, foggy, or hazy vision.
  • Tingling, a pins-and-needles sensation, and numbness.

There is no cure for MS.
