I wondered at times when i first started going when I was 16 whether what he did was appropriate or not, still wonder to this day, this doctor delivered me and my twin sister, so I knew him all my life and he was my family doctor.
However, I have a female now and she doesn't do what he did when checking me, and it's as quick as less then a minute.
I can understand why you aren't comfortable then but not every doctor is like that, can you get a female doc to do this instead ?
She shouldn't have thrown you out because you were too nervous, you had a right to complain about her treating you that way, doctors are supposed to be soothing, and gentle, allowing you to take your time to relax and also to let you know that though it may be uncomfortable it'll be kick.
Did it start to bother you after you went 20 yrs ago?
What caused your PTSD ?
