Hi Anjia
Sorry to hear you are still having problems.
I have no experience of this but I understand that you would not necessarily expect to recover completely from such a major operation as a hysterectomy in four months. I am sure others will be able to comment on this.
Have you though that the preparation of HRT might not suit you, and that the dose may be too low (if you were still having flushes)? It may be that using a transdermal method ie patch or gel would make you feel better. The sore breasts should subside after a while.
As you say it is disappointing that this one did not work but you should be able to find something that will suit you. Perhaps discuss with a specialist at your practice or ask to be referred to a meno clinic?
If you need any further help with this do ask and hope you manage to sort something out so that you feel better.
