Thanks for writing in to us.
If you have pneumonia
in 2008 (5 years back) it will not help doing a chest X ray
now, unless you have symptoms of pneumonia or any other chest complaints.
The toxins might have been flushed outof your system in 5 years time.
For your writing capabilities, I suggest you consult a neurologist
. They may ask you to get CT can or MRI
scan brain if felt necessary.
Hope this helps
