Am I okay or not ???

Ever since the onset of heavy winters here especially in December, I have been experiencing bad stiffness, joint pain, high levels of anxiety, and a burning sensation in my spinal cord.
So past sat 28/01/2023 I went for my monthly checkup with my neurosurgeon. Now in my last MRI of the dorsal spine, most of the lesions were gone and my brain MRI was also ok.

As per him, I am experiencing stress that is causing all these symptoms, whereas earlier I was told that this is a part of NMO cause earlier I was told this is a part of NMO.

I am badly confused if I have NMO or not, what are these things that my body is experiencing? what should I do ?? Is it normal ?? cause he has reduced the medications too? and my symptoms are nowhere close to being gone...
