Black marks symptoms and conditions

I have now had 18 venofer infusions over the last 16mo.Each time I receive them, within hours I have severe swelling of the IV site and up my arm.And also have severe itching also.It seems to take a week or more for the swelling,itching and pain to go away? The IV didn't come out of my vein,so not intramuscular.Is this normal?Or is there anything I can do to help these symptoms not happen at all? Thank you, P.

I have had my kenalog shot last April '08 for allergy relief. After a few months, I have noticed an indention and discoloration where the needle was injected; it is an ugly sight. After reading this article, I could assume that my menstrual irregularity, my period would come twice a month, was also another side affect of Kenalog.
Just like a lot of you, I would be interested in a class action against Kenalog, pls contact me.
