Somewhere in late 2000, suddenly one day everything I see became double. I thought it was my glasses and went to see an optician. They confirmed that the glasses were of the right degrees and suggested that I consult a doctor.
I went to see my family doctor and he advised me to go to A&E department at the hospital right away. Immediately thereafter, my hubby drove me to SGH (Singapore General Hospital). After much examination and tests, they concluded that there were nothing wrong with my eyes and suspect that it could be due to the nerve system. Hence they scheduled me to consult a Neurologist.
A couple of weeks later, I followed up with my appointment to consult the Neurologist. The Neurologist performed some simple tests on my eyes movement by holding a pen in his hand and moving it in different directions. At each location, he would ask if I see single or double. He also performed some simple tests to test the strength of my arms and limbs.
Thereafter, he scheduled me to do some blood tests, CT scan on the thymus gland and an electrical test (called Singer Fiber Electromygraphy or SFRMG). This electrical test involves inserting a small needle electrode, into the forehead muscle to record the differences in response time between a pair of muscle fibers. After all the result of the tests, the Neurologist concluded that my double vision was due to Myasthenia Gravis. The CT scan also showed enlargement of my thymus gland. At the same time, my blood tests also showed that I was having Thyroidism.
The Neurologist prescribed me with Pyridostigmine Bromide. Pyridostigmine Bromide prevents degradation of acetylcholine in the neuromuscular junction. It is usually given to improve weakness. But there is an side effect of this medication on me, there is always a blotted feeling in my stomach and I always had diarrhoea. I was subsequently prescibed with Propantheline Bromide to overcome this side effect.
