What my doc doesn't want to say and I don't want to ask

My recent visits to my endocronologist have been a little uncomfortable for some big reasons.  The 100 mcg of Synthroid that I take daily is helping me to stay awake, but many of the other symptoms have not been resolved.  Don't get me wrong, staying awake is fantastic, but I'm beginning to think that I may have come for the hormones and will end up staying for the tumor.

Last week, I had high blood pressure for the first time in my life. That, in combination with a 2 day menstrual cycle made me very nervous about what is going on with my body.  For the constipation, the doc prescribed Amatiza, but its $227 a month with insurance and I just couldn't see ponying up that kind of money for something I wasn't sure about. 

For the last couple of visits, my doc has been asking me some very strange questions.  He keeps asking me if I'm nauseous and I always say no.  Constipated - yes.  Nauseous - no. The constipation that seemed to be gettinb better with the Synthroid stopped getting better. I assume that is because some hormones would help anything for a tiny bit of time?   He also asks me if I'm dizzy.  Not really...but I guess I do have some bouts from time to time with temporary dizziness.  Stop that!  No blonde jokes!  I never looked up any symptoms for a tumor because I thought that maybe he would say something when he thought it was time to get an MRI.  I'm sure that he will - I am just beginning to think that the symptoms are starting to show up on their own.

Here are the general symptoms of pituitary tumors:
