Optic Nerve Edema: Causes, Symptoms, and Treatment Options - Ophthalmology

Optic disc edema

---

Initially, I thought the sudden changes and increase in floaters warranted a visit to the ophthalmologist, but the doctor said my eyes were fine.
However, he discovered that my optic disc was swollen and suspected that I might have elevated intracranial pressure, even though I did not experience headaches or other discomforts.
The doctor promptly arranged for an MRI, which came back normal.
Given my history of high blood pressure over the past few years, he referred me to a cardiologist to monitor my blood pressure.
I am currently taking antihypertensive medication, and he also referred me to a neurologist.
The neurologist felt that based on the ophthalmologist's diagnosis, a lumbar puncture was the next step, but my family did not want me to undergo that procedure, so it has been put on hold for now.
The neurologist mentioned that he did not expect to find significant abnormalities from the lumbar puncture and believed the swelling was likely due to my blood pressure.
I am considered obese, so for now, I am focusing on taking blood pressure medication.
The ophthalmologist indicated that about 70% of the swelling is likely due to elevated intracranial pressure.
If I do not undergo a lumbar puncture, I have been given one month to lose weight and return for a follow-up to see if the swelling has decreased.
It has been three weeks, and I still feel that my abnormal symptoms have not improved significantly.
For instance, I experience sudden blackouts in my vision, especially when I stand up quickly from a lying position or when I am reclining to watch TV.
However, if I rise slowly or in segments, I do not experience this as much.
It feels somewhat like the blackouts associated with anemia.
Additionally, I have started experiencing tinnitus in my right ear, which sounds like a vibrating phone, fluctuating in intensity, and occasionally changing to a rumbling sound in both ears.
Initially, I had floaters in my right eye (which are no longer abnormal), but now I have tinnitus in my right ear (which has persisted for over a month).
I often feel tightness in my right neck, discomfort on the right side of my head for a day or two, followed by a feeling of pressure and pain in my right eye, and then soreness in my right leg.
Symptoms seem to appear one after another on the right side over a span of four days.

Question 1: Why did the ophthalmologist suspect elevated intracranial pressure but not prescribe medication to lower it immediately to see if the swelling would decrease? After my MRI, I asked if I could be prescribed medication to lower intracranial pressure, and he only gave me one prescription, advising that the neurologist should handle the rest.
However, the neurologist seems more focused on my blood pressure and prescribed me antihypertensive medication.
To date, I have only taken that one medication for lowering intracranial pressure.
Question 2: I have researched the sudden blackouts in my vision and found information related to the carotid arteries.
My right neck has been tight for a long time, to the point of forming a hard knot, and stretching has not helped.
Recently, I have been using a foam roller to relieve the tightness.
I wonder if poor circulation in the carotid artery could be causing these issues.
Which specialty should I consult for this?
Question 3: I used to sleep soundly through the night, but since visiting the doctor over a month ago and not finding a clear diagnosis, I have been under significant psychological stress.
I feel a constant sense of unease regarding my unexplained symptoms, compounded by being unemployed and staying at home, which has intensified my anxiety about my health.
I now struggle to sleep well; even if I go to bed around 10 PM, I toss and turn until 2 or 3 AM without feeling tired.
I don’t know when I finally fall asleep, but when I wake up, I don’t feel particularly refreshed—just a sense of having slept and then woken up, feeling generally lethargic.
I don’t feel particularly fatigued, even though I yawn frequently, and lying in bed for too long causes me to gradually lose consciousness, only to wake suddenly.
At times, this happens repeatedly, and I still do not feel like I have had a deep sleep.
Should I seek help from a psychiatrist or psychologist for this aspect?
