I have been on the NuvaRing for about 6 months or so and have not experienced any real significant symptoms until this week. Wednesday night I had pain that started in my left leg. It was sharp, tingling, radiating pain that ran up and down my leg. The pain then went to my chest. The pain was a burning, sharp pain and I felt a lot of pressure in my entire chest wall; the pain extended all the way to my back and it go worse when I breathed in. This chest pain lasted for about 15-20 minutes. Then, it sort of became intermittent--it would leave, and come back and then leave and come back. Eventually it completely went away, but I was scared so I went to the ER to be assessed. My admitting blood pressure was 173/110. I was SHOCKED! The thing is, I have been having high BP readings consistently for about a month, averaging about 145/85 ish. They did an EKG, Chest Xray, and lots of blood work and took a urine sample. Everything came back normal! My first thought before I went to the ER was that it could have been a blood clot, but my leg didn't swell at all. They told me it could have been an anxiety attack, but I've experienced those before and chest pains associated with it, and this pain was unlike any pain I have felt before. I was just wondering if anyone else had similar symptoms? I have an appointment with my doctor on Monday and I'm thinking I'm going to take the ring out.
