Hi,
Noted your history of spotty vision from left eye, left ear tinnitus, headache and pain at the muscles attached to bones in neck.
Pulsatile tinnitus is most probable due to the following reasons:
Arteriovenous malformation in area of left ear or nerves.
Hemangioma.
A condition called glomus jugulare.
This can affect the vision in the same sided eye.
Can also cause headache.
Hence, I would advise you the following in such a situation:
Consult an ENT Surgeon immediately for proper clinical evaluation, examination and get the investigations like arteriography and as required.
Also consult an Ophthalmologist to know the cause and correlate with investigations along with ENT Surgeon.
A proper diagnosis alone can give you the best possible treatment.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT & General Surgeon
