Hello dear,
After going through your history, I believe you have some genuine concern and I will try to help you out of this situation.
First to tell you that the term
vertigo is not a disease, but a symptom. You described it write when you say you feel lightheaded and non-dizzy.
I would like to advice NOT TO GO FOR an Epley's maneuver. This maneuver is only for the condition called as BPPV ( Benign paroxismal Positional vertigo) which is due to deposition of calcium crystal in side the
inner ear and due to their mobility the sensory organs gets irritated leading to vertigo. But this episode lasts for few seconds only and subsides with rest. So you do not have this situation.
As you are having
blurred vision, heavy fore head and
nausea for 2 months, there is some probability of having some space occupying lesion in your brain. At this answer please do not get panic as condition like this must be excluded before progressing for any definite treatment.
In my clinic I advice patient like you to go for a
MRI brain.
Ct scan is not sensitive for
soft tissue. Brain is a soft tissue and MRI will be the gold standard investigation for that.
I hope I could solve your query. Please do not hesitate to clarify more doubts for the same situation.
Thank you for the way you are in my life.
Dr Ipsit Panda
