If you give the terp a heads up warning that you may sob during the exam, it will help them be prepared. Also, don't forget that the female terps have experienced gyn exams themselves, so they can empathize with your discomfort.
Like Botts said, maybe some anti-anxiety meds would help. Also, try some deep breathing and other techniques that help you relax. Even something as basic as a favorite stuffed animal that you can squeeze instead of socking the terp might help.
Be sure to be up front with your doctor about your stresses.
Good idea re: the warning about sobbing. It isn't a may - it is a will. Like I spread my legs and trigger a tear release button or something. It is like full body shaking sobbing too, not just little tears. I think once I know who the interpreter will be it will be easier. More anxiety if it is a new terp for me, less if it is someone I know.
Just because you mentioned the female empathizing thing I have to share this story...
All of these exams came about because of an infection I got after a minor surgery. I will have had 3 in 3 months come the exam in December. Anyway, for the first one it was in the emergency room and the interpreter that was on-call that night was male. I sent out a request to every female interpreter I knew trying to see if someone could come but no one was available and we settled for the guy.
He showed up, no idea what what wrong with me. I had someone with me for support and as she explained I could see him becoming less and less comfortable with the situation. Then the dr comes in to explain the exam and he is finger spelling every other word. "I -Dr. -----. #VAGINA# now-analyze. I-will - use - #SPECULUM# for - #OPEN# #VAGINA#. will - #SWAB# #CERVIX#. Today - you #PAD# or #TAMPON# you?. (For the men on this board, perhaps that was a little much,..sorry!) Anyway, this poor guy didn't have a clue.
I would respond, using classifiers and signs and he would have no clue how to voice it. It was pretty hilarious. He ran out of the room before the exam start (which was good). It is definitely one of my favorite interpreter stories ever. The funny thing is, in this community we have maybe 1 male interpreter to every 10 female interpreters. I have never had a male on-call before, or ever really worked with male interpreters before...just that once. What are the chances!
