I'm really worried because my dad's knees have been in terrible condition lately. I'm curious about the actual effectiveness of bone marrow stem cell injections. Since this is a plastic surgery forum, I assume you're well-versed in this information. It breaks my heart to hear that my dad is in severe pain every time he walks, unlike before. If anyone has ever had bone marrow stem cell injections given to their parents, could you let me know if the pain relief is noticeable? I really want to get it done at a reputable place, so it's giving me a headache. I looked it up and saw that Dr. Hong at Fresh offers bone marrow stem cell injections, so I'm curious to know what that place is like as well.
