milanchz,

Double spacing every line is just as bad. A double space every 5 or 6 lines makes it easier to find the start of the next line.

HBOT does not work for everybody. It is very expensive and rarely covered by insurance. The angiogenesis is well known due to imaging. The neurogenesis is not able to be documented. It is assumed due to the angiogenesis. How many dives (HBOT treatments) did you have ?

Etanercept is very expensive and invasive. Its use has been known for some time but it is an off-label use. Unless one has severe symptoms, the immune system risks make it a risky venture.
