Hello.I've had PCS for nearly three months now,I've had a very hard time but now I'm feeling a lot better less nausea fewer headaches....I'm still suffering from a whistling noise and ringing in the ears.I've had various tests on my hearing which appears to be normal...has anyone had the same experience and could give me some idea of the time it could take to get over this.....the noise isn't perpetual,usually stronger in late afternoon,evening,when it comes on stronger I feel a bit of pressure on the brain.....many thanks for any help.
