"Unfortunately, the 3 injections in my knee have done nothing to alleviate the pain, in fact, it is 3 weeks after all shots & my knee is slightly worse than before. I am hoping that by 6 months, when it wears off for those who experienced excellent results, for me, it will be back to "normal". Perhaps another brand will work better for me. The 1st shot did not hurt at all, but after 2 days, it became very painful, so much so I could not sleep. It did finally settle down, but I did consider not finishing the shots at all. 2nd was somewhat painful and left a small bruise. The third was just a little painful. Before the shots, I wore a knee brace during the day & do that now, too  My doctor says I am not a candidate for replacement surgery."
