recently had an mri of cervical spine for neck pain which revealed 6mmx8mm solid nodule in oral pharynx. did a CT of neck to look at it further and that revealed multiple nodules on a heterogeneous thyroid. ultrasound of thyroid confirmed several nodules, largest 6mm in upper rt and midline rt. last four years have been having heart palpatations intermittently. last one year menstual cycle has been off, bleeding in between cycle and during and after intercourse in middle of cycle. last 2 months period stoped all together. then started spotted for 8 days. then 3 days of severe pain and it turns out to be large ovarian cyst that ruptures. on 4th day , period begins with a rush. lasts 4 hours, stops for 36 hours, then continue spotting for 3 days and counting. can these things be related or does it sound like i'm in perimenopause?
