About 4 years ago I was showing symptoms of Myasthenia
Gravis. My GP was fairly certain of his diagnosis but he
sent me for tests just in case. I had various tests
including some antibody test (which I can't remeber the
name of) and an injection that immediately relieved the
facial symptoms and made me feel quite well for a few
seconds. The antibody test that was supposed to be a good
method of diagnosis proved negative.
My symptoms continued to get worse for a month or so but
then I ran out of a tablet I was taking for a different
problem and I went without them for a few days. The
Myasthenia Gravis symptoms dissapeared within a week and
they have not returned. The tablets were 5mg Oxybutynin
hydrochloride. I no longer take the tablets.
