My poor GP phoned me tonight and spent ten minutes trying to calm me down over everything - she says us girls are bound to have sore chests with exercise due to (her words) "having boobs that tend to bounce about and put a strain on your muscles". She said she doesn't think there is anything sinister - and my bloods are so far fine - but she wants to do a resting ECG anyway just for her and my peace of mind - some nurse is going to do it then she'll come through if there are any issues and then I have to see her the week after for a review I'm sooo happy they are taking me seriously for once
