I'm going to see my doc today, after I go to town to score some uppers and downers.
It suddenly changed earlier tonight, with a sudden ringing in my affected ear, a constant highpitched tone not unlike what happens in the aftermath of letting off a stun grenade in a sewer pipe whilst still standing in it (don't ask....missspent youth can get up to all sorts), but that ended up with everything going white suddenly, and nothing but the sensory system's test-card coming up, sudden ringing in the ears and nothing else coming through.
(moral of the story...think where the fucking blast wave and overpressure are going to go before chucking something like that down a sewer tunnel or similar confined space:P)
