Oh ((((sweetie))))) I'm so sorry you're dealing with all of this
My sister, who hasn't had a hyst, has been having yeast infections with practically every period. Her doctors are also baffled as to why this is happening. Then again, she's also having other symptoms, such as recurring cysts and painful periods, so there may be a number of issues going on.
I've also been dealing with increased IBS symptoms since my hyst... though, as I head into menopause, this has been slightly better in the past year or so. When I quizzed my wonderful ob-gyn about this, he mentionned that the bowels settle in in the space vacated by the uterus. This can take quite a bit of time. For those of us who have "sensitive" bowels, this can lead to increased symptoms
I never complained about PMS prior to my surgery. For 3 months after the surgery, my ovaries went on strike. When they went back to work, the PMS was simply unbelievable: I'd be confined to the couch, with a hot water bottle against my tummy and one against my back, just feeling miserable. Since I've practically stopped cycling in the past year, this is less of an issue.
I know how it feels to have doctors not take your symptoms seriously: that's a battle I've had to fight over the past 6 years
... and I'm still fighting it!!!
Is there a possibility of seeing another doctor? Sometimes, fresh eyes is all that's needed (that's the route I'm planning to take if the next appointment still doesn't bring answers).
