Finally, some of my medical testing has proved fruitful and is pointing in the direction of a formal diagnosis, which will hopefully lead to proper treatment. I had an MRI done last Wednesday, and by Friday, I was made aware that I have a cyst on/in my pituitary gland. If it is a problem-causing cyst (some create no symptoms), it would explain just about every symptom I have, as well as why my problems seem to be spread over so many different systems. Because the pituitary gland releases many of the hormones different systems of your body need to function, a cyst in it can be the cause of gastro symptoms, thyroid issues, muscular-skeletal symptoms, anxiety, blood pressure issues, and water usage issues. Basically, if they test my hormone levels and they are abnormal, we've hit the nail on the head, and I'll either have to take hormone replacements or suppressors, or antibiotics (this might have come from a sinus infection that moved to the gland), or get the cyst removed.
On that note, I do realize that I am very privelaged and very lucky to be able to have enough financial support from my family so that cost doesn't get in the way of my treatment, and I can focus solely on recovering instead of having to work when I am feeling awful. I'm also lucky that there is a doctor in my family who has been able to get me in to see specialists months before I would have been able to otherwise. Not everyone has these luxuries, and for them I am truly grateful. I still suffer on a daily basis from my illness, don't get me wrong, but it makes me all the more heartbroken for people who don't have the access to good insurance, money to pay for their expenses (which if you ask me are ludicrously high in the first place), and someone who cares enough to expedite their treatment.
I'll give more updates as my journey progresses.
