Miranda coil is associated with chronic uterine infection
or inflammatory diseases of the pelvis.
The symptoms you are experiencing are indicating for possible infections of the your genital organs and/or associated with urinary tract infection
So, I'd suggest to:
- do transvaginal/abdominal echo
- do vaginal swab testing
- urine analysis
Meanwhile, I'd advise to:
- take ibuprofen
or mephenamic acid for the pain
- take otc probiotics
- drink more water
- try not to have sex until you do the tests
All the best!
