I think a brain tumor is pretty unlikely. Why? Because this has been going on for twelve years. Malignant tumors grow. They don’t just stay the same size for that many years.
There isn’t a whole lot of spare area in your head to allow for much growth as there is in something like breast cancer which involves a larger area of spare mass.
I mean, where in your brain/head does a tumor have room to grow without noticeably affecting speech, memory and various motor skills or causing MAJOR painful headaches? A growing tumor is going to impinge on critical brain ares more and more as time goes on. Twelve years is a long long time.
I’m not a Dr. but plain old common sense tells me that much.
But if nothing will satisfy you short of a brain scan, then by all means find a Dr. willing to order one. Just be aware that you could be exposing your brain to unnecessary radiation thus possibly causing that which you fear.
I think it’s far more likely to be something far simpler like blood pressure fluctuations or the dehydration already mentioned. There are far simpler tests than a brain scan to nail down the underlying problem.
But, you really do need to find a Dr. who will not so casually dismiss your complaints. That may be difficult but you need to persevere, not just for this situation, but for the future as well.
This is just a thought, but perhaps you could find someone at your local hospital who could recommend a Dr.
This person could have one of several different job titles. Look for something along the lines of “Patient Advocate” or “Medical Ombudsman” or even perhaps a Social Worker (LSW) who is affiliated with the hospital specifically for handling patient needs of various sorts.
Some of the best Drs. I’ve ever had over the years in various places where I’ve lived have been from Recos from people with that type of job.
Even tho I’m not a hypochondriac, I had other major trust issues where medical people are concerned and the temperament and basic treatment philosophy of the Dr. was as important to me as their credentials or specialty.
These people work with lots of different patient types as well as most of the affiliated Drs. and have a pretty good idea who might be a compatible match with whom.
Try to get an appt. With someone like that. Explain your situation to them and ask if they can recommend a few Drs who might be good in dealing with someone with your tendencies.
Give it a try. It worked for me numerous times in the past. It’s not a 100% guarantee of a perfect match right away but it’s better than just constantly taking a stab in the dark and crossing your fingers hoping to find an understanding Dr.
