the one time shot is the dangerous one. It causes anaphylactic reactions and can not only ruin your knee further but cause immune system disorders .See my comments above
you are having a severe reaction. Please google synvisc severe reactions. and read the blogs. This shot is not safe and top knee doctors I have spoken to in CA and Boston ( New england Baptist orthopedic hospital) do NOT give people Synvisc. If you have a serious reaction ( swelling, immobility) you can die. Please read everything and run !
thats why I thought after my first injection. I had a SEVERE and evidently not so uncommon anaphylactic reaction to the shot. I called my surgeon in CA that I trust ( I moved to a different state) and he said," I NEVER give anyone Synvisc: It has formaldehyde in it as well as other allergens like Chicken combs. The second shot is what destroys peoples knees. Don't do it. Go google Synvisc second shot pseudo sepsis.
I had a one time Synvisc injection and it was so painful I thought I was going to pass out. It's only been 3 days so I presume it's normal to have lots of pain now. I'll update my results in a month.
Had Synvisc series last December. For a few months they seemed to help. Now, I'm almost back to the point I was at before the injections--lots of pain, swelling and stiffness. Going to make an appointment with the Regenexx people. I plan to exhaust every option before considering knee replacement.
I just had my first round of injections and so far so good
