Hello everyone. I need some help here. I started taking Yaz a month ago and have felt so horrible these past few weeks. I feel lighheaded all the time and have some headaches as well. Additionally, my neck and shoulders are SO sore...does this have anything to do with the YAZ? I used to feel like this before, from time to time...but it has increased tremendously since the pill. I also found out that my thyroid levels were abnormal from a blood test...do you think the pillhas anything to do with that? I stopped taking yaz about 3 days ago but still feel the lightheadedness and muscle soreness....some please help :-(
