The side affects I had were a change in eye sight and inner ear irritation. I never had the bleeding but apparently it can happen. My eye sight changed dramatically. I was pretty much blind as a Bat. I had glasses I used only for reading but soon needed strong glasses all the time. I also have very poor night vision now. They told me my eye sight would return to normal but it never has. We did however find out from the many eye exams I received that I had Cataracts. This was most likely caused by the radiation treatments and the hyperbarics caused them to grow. I must also mention that I went through 4 prescription changes for glasses in 3 months. The Optometrist loved me.
I also seemed to be very wiped out after I came out of the hyperbarics chamber. I usually needed to sleep. I am not sure if I healed any faster or better. What do you compare it to??? I found that the Doctors all differed on their opinion of Hyperbarics treatments. Some thought it may have helped a little. While others thought it work great and yet others said they thought it was a waste of time. Personally I felt better but it did not stop the necrosis of the jaw bone. I still ended up with it being replaced.
