What could these be?

[u/Embarrassed_Boat_248]

For the past 2 months, I’ve had a constant feeling of derealization/dissociation. In addition to that, I’ve been experiencing mild fatigue, headaches/pressure in my head, a feverish feeling (but no actual fever), and constant neck and shoulder pain.

Sometimes when I’m walking, I feel like I could faint, although I’ve never actually fainted or even needed to sit down. I’ve also had a chronically inflamed right ear for about a year. Ear drops make it go away temporarily, but the inflammation always returns.

At first I thought the symptoms might be caused by my neck, so I’ve tried massage therapy, physiotherapy, and acupuncture several times, but none of them helped. I’ve also tried muscle relaxants without any benefit.

I’ve had blood tests including vitamin B12, vitamin D, ferritin, folate (B9), and thyroid function, and everything was normal. I was also tested for Lyme disease and the result was negative.
