Another update: my father is now waiting for an appointment with an internal medicine department, the soonest which is in January (ooof). He's feeling understandably demoralised at the prospect of living with this pain for another 3 months without answers. All his bloods continue to come back with only mild abnormalities, none of which the doctors seem to consider significant; while scans/etc. have shown nothing at all. The only real red flag we've got out of testing is an elevated PSA, which is being followed up with a urologist and an prostate MRI (in 2 weeks).

Hopefully we'll get some more news soon.

I'm so sorry to hear about your current scalp pain! Is the neck/skull misalignment you're suffering from part of something bigger that you've been able to get diagnosed? I hope so.

We suggested a rhumatologist referral to my father's GP when we went back to see him, but he didn't seem to think it would lead anywhere, and instead suggested we wait and see what the internal medicine folks come back with. All well and good, if it weren't for the 3 month wait...!
