Have a good natter with yer Doc, Nick. The problem & beauty of GP's is that they are General Practitioners - not specialists, but far more familiar with your medical history than anyone else, qualified or otherwise (e.g. us lot!). They don't know everything (they're not specialists), but nutrition aside (black art), they know far more than any of us 'ere, right? ;-) Write down a list of questions so you don't forget 'em. Ask freely & ask any other daft thing that occurs as a result. A good GP won't get impatient; if they get impatient... Etcetera! It's your body & it's your health. So long as you're not being a needy, attention-seeking pillock (& you certainly don't sound like that sort!), a good GP... Etcetera. ;-)
