This morning we did our first session that was pressurised to 2.0 atms. You couldn't feel any difference in the air, it just took a bit longer to pressurise. I went in to the chamber with Mummy. It went well until the last 20 mins or so. It seems like I am getting more teeth - again and I was screaming... Sheila from Oxford Hyperbarics said that all the HBOT I am doing will speed up how long it takes for them to come through, so that is a good thing. Mummy spent lots of her time popping her ears. They were a bit sore, but we got through it! The bracelet Mum is wearing is to earth us in the chamber.
