Hi, I'm new here. I was diagnosed with an 8mm tumor a couple of weeks ago. My prolactin is only 61-82 (two recent tests - years ago when my discharge started the prolactin level tested as normal!) so it's not even 100% clear that it's a prolactinoma, but since I lactate, I guess we're going with yes. I'm a woman in my late 30s who has never been pregnant, though I did successfully breastfeed a sweet child adopted in mid-infancy, which I now know was thanks to the tumor. Anyway, over the past year I've gone from having virtually no headaches to having near-daily migraines. My neurologist said these have nothing to do with the tumor, but the neurosurgeon and endocrinologist both had a somewhat different story. My best guess is that the tumor size or effect reached some sort of tipping point, even though it's technically not pressing on anything. The MRI report does say there may be microinvasion of the cavernous sinous, and I have the sense that I started feeling this as internal pressure about nine months ago, before I had any other suspicion that there was something growing in the middle of my head, and before the migraines got going. Does anyone have experience with this feeling of sinus pressure, with the migraines, or with doctors' explanations of these symptoms as they may relate to the tumor? I understand that there may be mass effects (rare/impossible with this size tumor) and/or hormonal imbalances. So far the only thing that looks off other than my prolactin is testosterone (low), though I haven't seen my estrogen levels yet. Sorry this is a bunch of questions rolled into one. I'm on a seizure med for the migraines and it's making me pretty loopy, without working particularly well. Thanks in advance!
