I have been on HRT for about 7 years and I have had a great experience until last year. My provider upped my estrogen. I gained 10 -15 pounds in 8 weeks. After a year of getting it out of my system I am finally returning to my old body. Two weeks ago I went for my HRT. He upped my estrogen level despite me stating I wasnt having hot flashes, mood swings, etc. Within a day or two my hands started being cold all of the time, and they are hard to get warm. Now, two weeks out my nipples are getting extremely sore. I have never experienced the cold hand before. I did experience the tender nipples last year for the first time after he upped my estrogen and I gained weight. Could the weight gain, sore nipples, and cold hands be from having too much estrogen?
