There have been quite a number of posts here where posters say they cannot use HRT. In many cases, this is based on misinformation by them or their GP.
The only absolute reasons not to use HRT are
recent stroke or heart attack
recent breast cancer
recent / current serious liver disease
active blood clots in lung/leg
If this applies, then your specialist should be working with you offering you alternatives which could be herbs, acupuncture, ADs, meditation, CBT, lifestyle changes such as exercise, yoga, dietary changes, etc. It's not acceptable to be told you cannot have HRT but then not treat you for menopause symptoms.
