Otolaryngologist or neurologist?

I’ve recently been feeling a headache-type sensation in what feels like the center of my head, or at the tips of my ear canals – a semi-sharp sensation, not necessarily pain but definitely not comfortable; I suppose it is similar to a tension headache. I think it’s due to playing music over the past month (singing, wearing monitor headphones for long intervals, etc.—yes I know this is bad). My other symptoms include a sensation of confusion from time to time which lasts 3–4 seconds, and generally feeling like I’m in a brain fog. I don’t want to waste time or money getting various referrals so I’m wondering if I should see a neurologist or go back to my otolaryngologist, who I had seen for BPPV (benign positional paroxysmal vertigo). After hours of googling my symptoms I can’t find anything bearing resemblance. Maybe I’m slowly losing my hearing? God I hope not. I’m a musician. Or brain cancer? Anyone with any insights?
