Suggest Treatment For Flu Symptoms And Numbness At The Finger Tips
An involvement of the nervous system to consider.
Detailed Answer:
Hello,
In some cases after a viral infection, this infection, or autoimmune changes after it, may affect the central nervous system or peripheral nerves as well.
So, since there is poor balance and falling, an involvement of the spinal cord (transverse myelitis for example) or peripheral nerves ( polyneuropathy ), etc. should be considered and evaluated further.
It is necessary for your son to get evaluated by a Neurologist and, most likely, by imaging tests such spinal cord MRI, nerve conduction study in order to understand your son's condition better.
