Waiting for solid answers when some weighty possibilities have been mentioned has to be the hardest thing. Hopefully after the MRI they'll give you any results in a timely manner. You know, all those symptoms don't have to come from a singular diagnosis. Maybe they do, but you really could have a few different more minor conditions at work. Have you been evaluated for the individual symptoms? For instance, the thirst - checked for diabetes? The difficulty swallowing - been evaluated by an ENT doc? Sleep issues - had a sleep study? Fatigue - Thyroid, diabetes, sleep disorders, anemia been checked? Memory trouble - common with some sleep disorders. Anxiety - not unusual with some sleep disorders. What about meds - could any of your symptoms be side effects of a med? I've had a med cause involuntary movements. I have a sleep disorder called Periodic Limb Movement Disorder, and the trouble it caused with my legs and lower back had the doctors stumped for a long time. Sometimes the answers can be elusive, but the process to diagnosis is often by process of elimination. Hang in there till you get answers.
We've been through the process of elimination and its been an ongoing thing for a few months now trying to find out the diagnosis so to speak. Its truly a nightmare and time consuming. I will be prescribed a med called Levo something and if the tremors stop we know its PD and if they don't stop we know that it is not PD. I just want answers so that I can get on with things and I have two children and a husband and this is very scary if you know what I mean and Im sure that you do. Thank you so much for your input it really means a lot!
