IT's an individual choice according to your needs and budgets and experience with different treatments as we all have different body chemistry so medication has variables on how effective it is. I have spoken to researcher from a large pharm company in US and yes, it would be a miracles if medication worked the same with everyone. In same respect I know people who have been on drugs for years to no affect. Why they continue taking them when they don't help at all is beyond me. My understanding my case in particular my anti rejection meds for my kidney transplant have given me side effects other do not have. So I have given up in trying to solve my pain. I just deal with it as excruciating as it may be. Personally I believe stems cells, your own, which are clean and applied in to your body have the potential to heal. Why do stems cells from umbilical cord and other kinds of stem cells being used for heart and brain conditions? They serve many purposes? Stem cells in 2023 and beyond in my own opinion have great possibilities for many illness and if they are your own how can they harm you? Many countries around the world have innovative therapies we can only dream about. In research studies you pay nothing, IF a patient goes to a center which hopefully will be approved by FDA or hospital in research in a particular ares, Yes, it's costly but if they save. your life or that of a child in my opinion hold great promise. IF one can afford why not try them? Many athletics swear by them. Drs and those in medical research in US. also do not promise anything beyond a little bit of hope that a condition can be treated to at least be bearable if not managed so people can live a semi normal life. Best of Luck.
