I switched to Yuvafem I took the product for 2 weeks everyday as instructed and then switched to 2 times per week for about 2 weeks. I noticed muscle aches and joint pain, headaches and vision issues. I then looked up the side effects and realized that I had several of the side effects that appear to be rare. I called the physician that prescribed it and went back to taking Premarin. I have been off the medication at this time for a month and I still have several of the side effects that ensued while taking the medicines. My question is this, will the side effects go away or will this be a permanent issue?
