Does Thirstiness Occur With Neck Alignment Issues?

I woke up with a headache. My scull was so tight. I was also very tired. I felt hung over and I should not have felt that way at all. I slept a lot on Sunday and felt somewhat better on Monday. Went to work around eleven. While there the pressure on my scull like someone was hanging off it made me feel like I was going to get sick to my stomach. Made it thru the day and just went to bed when I got home. Got up Tuesday. Felt more rested but still had tightness down the back of my scull, neck. Scull soar to the touch especially at the base. I m thirsty. Am taking Advil. One pill every 4 or 6 hours. 200 miligrams. Made it thru Tuesday but had diarreah. Wednedsay afternoon went to Physical therapy. Told me neck is out of alinement and have very tight derma. I m thirsty and feel like I m somewhat poisoned. that might sound crazy. I have a slight headache like I m still hung over. I m tired. Went to work Thursday. Very tired when I got home. Ate but don t have a big appetite. Saw PT today. Better movement in neck but thirsty and tire. It this just neck issue ( I do have a history of neck issues) or something else? I have not had this thirsty thing with any of the other neck flare up or diarreah. I have a doctor appointment but not til late next week.
