I was addicted to earplugs for sleep to the point where I couldn’t sleep at all without them. A doctor told me that wearing ear plugs for anything beyond the use of avoiding very loud noises can cause ear blockage and tinnitus (both things that I’ve had since that I don’t think I’ve had before though I’ve had sinusitis and head congestion/dizziness before I was using ear plugs so think that’s unrelated). Ear plugs seem to help my dizziness a little but I’d like to avoid having over-sensitivity to noise (as already have that with my migraines and working on being calmer around loud noises) or other conditions. Below is from The British Tinnitus Association:
"Ear protection should not be used if ordinary, everyday sounds are uncomfortable (this may be hyperacusis or oversensitivity to sound). If earplugs are worn for blocking out such sounds, it can actually make hyperacusis worse.
Hyperacusis is an increased sensitivity to sound. If you find that everyday or ordinary sounds are uncomfortable, you may have hyperacusis. Whilst it might seem natural to want to block out as much sound as possible, avoiding sound can actually make hyperacusis worse. Talk to your GP about this and ask for a referral to either an ENT Surgeon or Audiovestibular Physician who will be able to suggest management options – often, using sound (in a very controlled way) can improve hyperacusis."
