What Causes Blurred Vision And Disorientation While Treating Flu?
It is a possibility to be checked.
Detailed Answer:
I read your question carefully and I understand your concern.
The symptoms you mention are not very specific, meaning they could be cause by many different conditions, from viral infections, anemia, metabolic and hormonal alterations, nutritional deficiencies, rheumatological conditions. However since it's been 3-4 months I suppose most common causes have been ruled out by blood count, glucose, liver and kidney function, hormonal panel, thyroid function, vitamin B12 levels. If not already been done I would suggest testing for rheumatological conditions like lupus, rheumatoid through tests like antinuclear antibodies, rheumatoid factor, XXXXXXX antibodies etc.
If indeed all that has been done and results as normal then less common causes should be considered. Whether tick borne conditions can produce those symptoms....yes they can. In particular Lyme disease is common and manifest that way. A rash is present initially but not always and may be missed at times. So it is reasonable to have some additional blood tests on that regard to check for antibodies against Lyme bacteria.
I remain at your disposal for other questions.
