Multiple Scelerosis is a chronic disease that damages the nerves in the spinal cord and brain, as well as the optic nerves. Sclerosis means scarring, and people with MS develop multiple areas of scar tissue in response to the nerve damage. Depending on where the damage occurs, symptoms may include problems with muscle control, balance, vision, or speech.
MS Symptoms: Weakness or Numbness
Nerve damage can cause:
- Weakness in an arm or leg
- Loss of balance
- Muscle spasms
These symptoms may lead to frequent tripping or difficulty in walking.
More than half of people with MS experience a vision problem called Optic Neuritis. This inflammation of the optic nerve may cause blurred vision, loss of color vision, eye pain, or blindness, usually in one eye. The problem is usually temporary and tends to improve within a few weeks. In many cases, vision problems are the first sign of MS.
