Hi I have now had full bloods checking for everything including thyroid and iron levels. All is normal, if anything my thyroid levels are low. This past week I have had 3 full days of the worst headaches and then a day of diarrhoea. On Tuesday I started a heavy painful period out of the blue so am now thinking it is definitely menopausal symptoms. My GP agrees and is sending me for a scan and to see a Consultant. She says it is not normal to have a period out of the blue at 59 after no bleeding for circa a year. Why has my hrt stopped working? I feel like I am back at the beginning. Literally every symptom has come back - night sweats, anxiety, headaches, aching joints, hair loss and severe insomnia.
