I had a sub total hysterectomy November last year and now take hrt daily. The hrt makes me feel foggy each morning and the endometriosis pain is already beginning to come back. Some days I feel so awful, I am waiting for the day where I wake up feeling refreshed from a nights sleep. Has anybody else been through this so soon after op. The constant did say that I was terribly stuck together due to the endometriosis but for it to be back so soon is gutting .
