... but it flowed out of the needle way too fast.. He has since developed a lump that feels attached, like w/ a cord, Dr. said, and extreme pain and numbing down his leg where siatica is. If I massage his legs and rub toward feet, the pain is unbearable til i rub the blood back up. He said he was getting a muscle cramp, but what I felt was a lump, in the quad, trying to travel toward his feet. White-hot pain. I literally stopped the lump and pushed it back up. I am so scared. He is having the small, injection site lump removed tomorrow, but I would like to know something now. Help! We believe the two lumps are related and it started w/ injection site.
