Hi Ann
Worry not; I think this is standard practice of you're on HRT. My last yearly check with the practice nurse was very straightforward - just a few questions about general health and they checked my Blood Pressure, and weight before renewing the prescription. I think GP practices have to be seen to have reviewed the HRT every so often, especially when you don't have problems and are not at the GP regularly with other ailments.
All the best, ER x
