Hi I started getting right sided headaches 2 months ago along with tingling and burning sensation. doctor said its occipital nueralgia and prescribed nortryptili 10 mg. after using it for a month, i changed to despramine and saw slit vision on my left eye as soon as i got up for about 30 secs..i have for 3 weeks now and doctor says its iih. when they did mri for my headache they saw an incidental finding of an arachnoid cyst in my left temporal fossa and said it has nothing to with any of my headaches. having a spinal tap tomorrow..no infections on blood work....can i get pregnant with iih
