Hi Drummer girl , how long ago did you have your scan and what type did you have?
Your pain sounds similar to mine which I had pre HRT which I started last July ( femoston 2/10) , it seemed to ease for a while but then started again about 6 months ago. Started with heavy irregular bleeding in March and spotting. I just put it down to being peri and my hormones being all over the place. But in June my GP wanted me to come off HRT and get a scan done.
I had an abdominal ultrasound scan and transvaginal scan about 2 years ago for irregular bleeding which showed nothing.
Had another scan early this July and it’s shown fibroids and thickened womb lining. Apparently fibroids can grow quite quickly and a transvaginal scan , although unpleasant, is more accurate at detecting issues.
I’m currently waiting to hear from the hospital as I’m supposed to be having a hysteroscopy but I requested it under general anaesthetic so it’s delayed things.
Abdominal pain including back pain is definitely one of the symptoms of fibroids but I’m guessing with your HRT you don’t have periods any more?
