Has your Hematologist said sticky platelets are the norm? Is you husband on a baby asa or a blood thinner..I agree not to go onto Dr. Google but there are sites that are very informative..For instance if you go on you tube and search, in your case, ET you'll find MDAnderson, Sloane Kettering, etc hematologist oncologist who specialize in just your specific disease with the caveat always discuss with your Doctor. I was surprised one day on a You tube pod cast to have my Dr. from MDA discussing PV..I believe an educated consumer is a healthy thing however, I don't do anything without first discussing with my Hematologist.
