I visited the doctors office today as I am trying to determine the cause of a rising himocystine level (17, 45, and now 69) over the course of 2 years. I use kratom daily as well as whip its (non medical grade nitrous oxide) as well as prescriptions for eliquis 5 mg, b-12, b-6, and folic acid. My research of Kratom produced only vague inferences to increased viscosity of the blood and zero studies done. My doctor believes that the nitrous oxide is not affecting my blood and is not familiar with Kratom, nor does he seem interested in researching it.. I use these two drugs for chronic joint pain. I am hoping that I might gain some clarity on the topic of my rising himocystine levels as my doctor seems to have given up. Thank you in advance for your time and any information that you might be able to share with me.
