Headaches- When to call Onco

Edited to remove stuff that prob wasn't relevant.

Symptoms and Tests:

Dec 2016: Neurologist ordered MRI head and neck for Lhermitte's sign (a painless shocking sensation of gen bending neck). Test negative. Flexion neck X-ray positive for 2mm c2-c3 subluxation. Treated with hard collar for several months. Lhmetties sign mostly gone but subluxation was the same. Neuro rec'd to see Spine surgeon. I never did.

Mid May had Chest CT-clear

July 10: chest X-ray clear. Blood work all fine (including heart).

July 22: woke up with headache. Over next 5 days got worse. On 6th day also developed upper back pain (pretty bad). ER did Head and neck CT with contrast which was negative.

Okay now for my narrative:

That was 13 days ago. Back pain has happened a couple times since but mostly is fine BUT I have not had one day with no headache and even when it doesn't hurt it feels full. Or like someone is pushing on the top of my head. I also have had pretty severe ear pain but no fluid or infection. NP at PCPs thinks it's related to spine.

I have not called my onc. i don't think it's cancer related but sometimes I wonder if I'm In denial. I had NO pain with the subluxation at all, no headaches, no neck pain- nothing. And I've had the subluxation for 8 months. The headaches are new the last 2 weeks.

Would you call the onc? I don't have to worry about my brain with the CT right? Anyone had something similar happen? Opinions welcome.

Ps- I had Stage 3 but pCR at surgery Dec 2016! Woot woot.

Ps again- I forgot to mention that a week ago I had a few episodes where my thumb twitched. It wasn't fast and it was About 30 sec each. Happened 4 times that day and hasn't happened since. I THiNK it was a muscle twitch but not like one I've ever had before. My whole thumb moved.
