That is quite the list! Possibly it is a few things going on rather than ALL being from one source. Could you have irregular migraines? Muscular issues can create that as one possible reasons. I had some of what you talk about due to issues with a neck injury I had from a car accident. Small areas start to stiffen such as right behind my ear. Pain and stiffness then happen going into my neck and up into my head, tension, headache, eye pain, etc. I've also had inner ear tube, or Eustachian tube dysfunction which causes dizziness, ear fullness, etc. And honestly, some of what you describe sounds like it could be related to anxiety. Any of that sound plausible to you?
Sereatoni shock syndrome or some type of medication interaction. Adderall and Trazadone cane generate a similar response. Look into seratonin shock and then identify all medications and supplements you take to look for interactions and discuss with doctors AND pharmacist. MDMA (ecstasy) has been known to cause this As well for days of weeks after use especially if taken in concert with certain cns stimulants or anti depressant medications.
But I agre with first response that it could be a myriad of issues and I assume the spinal tap is to rule out meningitis (or test for lsd!) Seratonin Shock Syndrome should be ruled out before a tap... update us if possible we will be sending positive vibes :)
Similar symptoms to what I have had. Have they checked your iron, haemoglobin levels and vitamin B12.
My iron level was 3 (healthy range 20+)
My haemoglobin was 5.2 (healthy range 12-18)
Had a blood transfusion, iron transfusion and a B12 injection and doing much better now.
