I too have a lady doctor and believe me she isn't hearing anything she hasn't heard or seen before. Didnt have the same problem as you, but had a bladder problem, she had no problem in describing what they were going to shove down my japs eye and up my rectum etc. Really no need to be embarressed about it at all. She knows your medical history, there well may be some physiological reason behind it. That sort of medication you really shouldn't take with out your docs say so, if you have high/low blood pressure etc. Just blurt it out when you go and see here, she won't bat an eye
Come in she said "I'll give you shelter from the storm "
