Hi, I'm new here but I've been reading many of the posts and I was just wondering if anyone had problems with sinus congestion or dizziness/balance problems when using BC? I am currently on nuvaring and have been using it for about a year. For the past 7 months I've had constant sinus pressure and congestion, but I had allergy tests and I'm not allergic to anything! Is there any correlation between BC (more specifically, nuvaring) and nasal congestion and/or dizziness? By the way, at the beginning, the dizziness and congestion were so bad that I couldn't even get out of bed and I had to go to vestibular therapy to regain my balance skills. All of the doctors I have seen can't give me an answer because every test they do (EKG, MRI, ENG) says I am a perfectly healthy for a 21 year old. The nuvaring is the last option I have to explain these crazy symptoms! Thanks in advance for your help and sorry for the long post! :)
