In May of this year I went to my optometrist for my yearly eye exam and to get new prescriptions for contact lenses and glasses. During my appointment, the optometrist noticed some optic nerve swelling, which he told me could be a symptom of pseudotumor cerebri and said that he would be referring me to a neurologist.

I was finally able to see my neurologist earlier this month and she had me get some MRIs done, both with a dye injection and without. She told me that my MRI results came back "perfect" and that all "veins and openings were clear and looked great". 

She still wants me to get a lumbar puncture/spinal tap done even though my MRI results are good. I am extremely anxious about this procedure. I am curious if it would be worth getting a second opinion, or if someone could explain in further detail why an LP is needed when my MRI looks okay. I'm not doubting my doctor, I just really don't want to get an LP if I don't have to.
<bot>: I have optic nerve swelling but my MRI results are clean. Neurologist still wants me to get a spinal tap. Should I get a second opinion?
