Hi,
And large pieces of information are missing that are needed to make a good advice. First, no, Fish oil, more commonly known as cod
liver oil, is usually safe in most people and is not known to cause the brain effects that you mentioned.
Now, I think there is some lesion found in your brain
MRI, and I would like to know the exact report or see the scan before I can comment on it. But yes, that lesion can be a cause of not only your symptom of the arm, but also the heaviness of the head and imbalance when you walk.
Since the exact report is not mentioned, I will not be able to conclude what may be the cause of your symptoms. It could be anything ranging from
stroke and
TIA, to
demyelination such as MS, to infections like NCC. So without the report or the scan I cannot comment on the treatment.
I have tried to make it as simple as possible. Let me know the report/scan and I will try to help you further.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Saumya Mittal, Diabetologist
