Thank you for your answer.
I have been taking my pulse/rhythm during these periods and not detected any abnormalities.
Would I experience any other symptoms with an inner ear problem?
What autonomic nervous system problems are you thinking of or would these be only on the differential list if there were heart rhythm disturbances?
What autonomic dysfunction are you thinking of?
Do I need to stop the Climagest (am reluctant to do so and have been on it for about 2 years and not experienced side-effects)?
