Hi

I have had five specific bouts of neurological symptoms over the past ten years, approximately 2 years apart.

The symptoms are 'loss of balance', stiff legs/arms and difficulty walking. On two occasions I also had 'slow moving arms and legs' and a symptom where my right arm and / or leg would stop for a microsecond before continuing.

The bouts usually last for 3 months and slowly improve over this time, with rapid improvement in the first few weeks. I am usually left with some degree of compromised balance and stiffness afterwards, although no big deal. All bouts were preceded by infection, injury or trauma.

Most testing is negative (including multiple MRI and antibody testing). I had an abnormal single fibre EMG result in the ocular muscles, but no overt ocular symptoms. I found that magnesium supplements can cause muscle weakness within hours, as can regular physical massages.

Could this be myasthenia? I have seen five different neurologists who have not made a diagnosis.

Thanks
