Gallblader symptoms and conditions

I have a history of stomach problems (H. pylori infections and acid reflux) and was doing great until I started the nuva ring. Since then, I get sick every night- my stomach hurts and i feel nauseous and I just feel cruddy. I don't know if these things are connected- anyone else have stomach pain with the ring? I also tried to skip a period with the ring and my period has been going on for a week now, when it usually lasts about 4 days. grrrrrrr...

I was in the hospital to have out my gallblader in April 2006,
They had it in my IV. My arm started iching right away, and in mins, you could tell where all my vains was. They were turning bright red. Then they started blustering threw my skin, in a swelled upline with the way the vains ran. My husband got the nuse who then pulled it out of my arm right away, and flushed my system as fast as she could. Then later on I had my operation.
Six months later I got a knot in the side of my neck, and I wonder if its related to that happening to me. (If it could cause my vains to look like that. I am wondering what else it did to my insides.
