My 37 yo daughter has recurring fevers (lasts 1-2 days) around her period. She just finished her period a few days ago and now has a fever of 104.7. Last month she had a fever of 103.5. This has been going on for almost 1 year. She had a laparoscopy done last May that showed a minute amount of endometrial tissue, but otherwise, normal.She did have an MRI that showed after small ovarian cysts bilaterally. No one can offer any relief or explanation. She is not on any regular medications except wellbutrin and adderall. She takes Advil for the fever which helps eventually.
