Hi. My 8-year old daughter has gotten her second shot of Lupron in her thigh. She gets them every 3 months for precocious puberty. Her thigh is still a little swollen and painful--not terribly painful but probably like a sore muscle would feel and she is limping slightly because of it. She had the injection 3 weeks ago. I took her back to the doctor yesterday and the doctor didn t seem overly concerned as it is not infected. I m still worried. The first time she got the shot it hurt the second day and that was all.
