My doctor has instructed me to stop taking Premarin because of my age of 65 years due to cancer risks. I also learned that by turning 65 (in the U.S.) insurance will no longer cover. As with most women related issues, we don't count. I started Premarin after a total hysterectomy at age 35. Anyway, I'm experiencing heart palpitations, heat ache, body aches, night sweats, and loud ringing in the ears. All of which (except for the ear ringing at a lower sound) just happened with stopping the premarin. Can anyone tell me how long I can expect these symptoms or if there are any natural supplements on the market that are safe?
