I am taking 20 Hyperbaric Treatments in an effort to increase my body's ability to make blood platelets. Hyperbaric increases the number of stem cells in a person's body by 800%. I hope the stem cells can fix my bone marrow so I make more platelets. If this approach to ITP is successful I will let everyone know. The cost of the 20 treatments was $3,700. Insurance does not pay. The medicine people in the USA only think hyperbaric is good for a limited number of health problems. In Europe and Russia they use hyperbaric for many diseases.
