I have been having upper respiratory and sinus problems over the past few months and it all seems to line up with starting the Ring. The first month was alright and since then I have had this series of severe cold symptoms, my glands are swollen and I'm coughing all the time, I'm weak and run down. I was put on an antibiotic and that was during my off week. I was better by the end of the week and put the ring back in on Friday- started getting sick on Saturday and worse Sunday-Tuesday. I did take the ring out on Sunday, but my doctors seem to think it's just a bad cold season. However, I look at the package insert and see that Upper Respiratory Tract Infection and Sinusitis are listed as side effects. How would they be listed if there weren't other people suffering from this too?!? After finding this site and reading about other side effects, I'm taking a break from birth control pills/meds. I feel like I don't understand my body at all and I need to take back control from the doctors and their magic medicines.
