I began Yaz 10 days ago. This was my first time being on the birth control pill at all, and immediately at day 5, I experienced numbness in my left arm and leg. I saw my GP on day 7, and he wasn't concerned but said to stop taking it. Then on Day 8 I saw my gyno he switched me to Nuvaring, but I continued to have the same problem and developed a headache. He told me to take the nuvaring out and go to the ER. The ER determined that I didn't have a stroke, or a blood clot, which was the main concern. He said if it isn't better in a few days to make an appt with the neurologist. I went ahead and made one for next week because the numbness hasn't improved. I'm worried. I also read where it could be Vitamin B-12 deficiency so I'm going to get some Vitamins to take until then. I'm worried.
