not a dr and dont play one on TV either....
but the first part sounds like the blockage of sinus problems...and the other parts sound like further testing for your sinuses....then the one part...does talk about a spot but talks about migrane related....is how I read it...

good luck, sorry they mailed it...I wouldnt jump to hard on the MS or other stuff reading...till you call...thinking between the sinus blockage and migrane idea....but definately call Monday...bummer they mailed it..thinking they werent too concerned then.....hugsss and welcome, sarah
