NuvaRing and foe

I lasted for one week on Nuvaring.... put it in on 7/26, took it out on 8/2. I expected some slight hormonal type side effects while my body adjusted to the ring... this is my first hormonal BC ever.... Saturday, I couldn't keep my legs still... jittery and anxious, cramped and so uncomfortable. Yesterday I got a very bad dizzy spell while in the shower. Over the next several hours, the dizzy spells came more frequently and got stronger, to the point where I felt I was going to faint. My heart was pounding, I was sweating, my chest felt heavy, and the room was spinning. First spell was at 6:30 am, I took the ring out at 11:00. The spells continued for the next 1/2 hour or so, and I noticed a huge welt above my ear.... hot and sore to the touch, radiating pain down into my neck. I've also had a stiff neck for days, which I didn't attribute to the ring until reading someone elses posting here. I'm feeling better today, though the symptoms have not completely gone away. I presume it will take 7+ days for this crap to get out of my system.
