I am 55 years old and normally I am a fit individual, with lots of energy. I have had a Mirena coil for about 8 years, mainly to control my erratic bleeding. So far it has done very well, however, I started having hot flushes about a year ago. They became increasingly annoying, disturbing my sleep. I saw my GP, and they prescribed a low dose of oestrogen in tablet form. That was six months ago and the night-sweats stopped immediately. Now I suffer from horrendously painful cramps and, since last week, I've suffered every day.
