I have low tinnitus days and moderate tinnitus days. Sometimes it spikes from a loud noise and stays high for a couple of days. Other times it spikes or comes down during sleep. Day before yesterday night it came down during sleep and today afternoon I slept with out proper neck support deeply and it came back up again. Makes me wonder if the issue is with my neck though my hyperacusis and tinnitus started after a couple of days after clubbing.
