Soft Chamber HBOT (No Oxygen) for Hyperacusis with Ear Pain

[messedupmyears]

For budget reasons, I cannot afford the hard-shell HBOT with oxygen. However, I've found some places that offer lower-cost HBOT, which uses only about 25% oxygen instead of 100%. In this case, it would rely solely on the pressure (around 2–2.5 ATA) to potentially relieve symptoms.

Would this treatment still be beneficial without the oxygen component? I'm experiencing severe pressure in my ears and painful hyperacusis, which worsens directly in response to noise exposure.
