Can A Long Lasting Viral Fever Cause Leg Pain And Hydromyelia?
Thanks for the query.
You have to understand my limitations here without an examination after your doctors were not able to find clues.
I shall try to give my opinion here.
Leg pain and weakness after three weeks of an episode of viral fever along with your son's symptoms suggest a possibility of post viral complications.
Probable conditions would be:
1. Simple post viral neuralgia
2. Guillain-Barré Syndrome
The above conditions are due to a disorder in the immune system where the protective immune system starts damaging our own body components and thereby causing problems.
Simple Post Viral Neuralgia
This is a common condition after an episode of viral fever. It subsides on its own within short period of time. A repeat follow up is needed frequently till his symptoms gets better.
Guillain-Barré Syndrome
This is an immunological condition which affects the nerves. The symptoms of which would be weakness and burning sensation of limbs after a period 2-3 week following an episode of viral fever this can ascend to the upper limbs. This requires an immediate attention by a Pediatric Neurologist. You would also require an CSF analysis to confirm this condition.
Regarding the MRI report:
Hydromyelia in the upper spinal cord.
As your doctor said it has nothing to do with your son's leg pain as the lesion is the upper part of the spinal cord. I would also agree with it.
Regarding your query of the possibility of damage to muscle, nerve or bone after an episode of viral fever. It is possible from the possibility which I have explained above.
I suggest you to get a referral to a Pediatric Neurologist.
Hope I have answered your query. If you have any follow up queries I will be available to answer them.
