Hi will try to make this brief... In April I had my hrt changed from premique to climaval l also had my thyroxine increased as I'd been under medicated .... Hrt was changed as it was a dual hrt giving to me following hysterectomy after endometriosis was found... Hence dual hrt.... When l seen the endo regarding my thyroid levels he spoke to a gyny who confirmed l should not of been on the dual hrt as long as l was 4 year! 6 month would of been sufficient then I should of been put onto estrogen only..... For the last 8 days I'm having lots of palpatations all day long, also some hot sweats..... My thyroid levels are in a good place... I'm very confused as l was told the climavil 1mcg dose is higher dose than the premique l was on ( high dose) So why after 4 months is this starting anyone know? Thank you x
