You didn't mentioned which type of fibroids you are having.
The possible causes for your symptoms according to gynec point of view are,
1. presence of subserous fibroid:
subserous fibroids grow from the outer surface of the uterus. When they become large in size they will exert pressure on surrounding structures.
If they are attached to the uterus with a stalk, they are called pedenculated fibroids,
sometimes they will attach to surrounding structures and get blood supply from them and get detached from uterus. These are called wondering fibroids.
The symptoms of subserous fibroids are:
pain in the abdomen and pelvis sometimes radiating to back,
sensation in the abdomen,
if pedenculated fibroid or wondering fibroid attaches to the urinary bladder
it will lead to increased blood supply of the bladder further leading to symptoms like frequency of urination.
So, I am suspecting that there is a chance to have subserous fibroid with symptoms.
As you told you are near to menopause
, after attaining menopause the fibriod will shrink and symptoms will decrease. Till then you can manage with analgesics.
2.presence of pelvic inflammatory disease:
in this also you pelvic pain
radiating to back,
occasional fever because of infection,
increased blood supply to surrounding areas like bladder will lead to urinary symptoms.
Here combination of antibiotics and analgesics will decrease the pain.
But if it is unbearable pain better consult your doctor again, take one ultrasound
to determine any fresh cause for the symptoms.
