I had the shot mid August 07 for a case of poison ivy. At first nothing seemed wrong. A month later, I was still itchy, but not where I had poison ivy, on my scalp, elbows, and my right palm. My period was off by two weeks, but nothing like a 4 week period. Yesterday I had severe aching in my left quad and hamstring area, though I haven't done anything strenuous lately. Tonight I noticed the huge (maybe two inches long, not really round, but sort of like a finger was pressed into my skin) indentation and got really scared. Just as so many others have posted, I was not warned of the risks of receiving this shot. I am a little scared about the indentation continuing to grow. I can't believe so many people have been adversely effected and so many doctors downplay it as just one shot. I feel like I've been duped and conned. I will definitely tell all of my family and friends never to try this snake oil. What can we do? Has anyone contacted a lawyer for a class action?
