So, I've been on carbimazole over a year (awaiting total thyroidectomy) and I know the drill - sore throat = urgent blood test, just in case it's agranulocytosis. Started with a sore throat last night, no better this morning so went to my local urgent care centre (GP is shut for bank holiday weekend). I did the usual "it's probably nothing" and dithered a bit about going.
Saw a doctor...she basically interrogated me about why I was there and what made me think I needed a blood test and why it couldn't wait til Tuesday. Eventually I just pulled up the BNF page for carbimazole on my phone and showed her the "important safety advice". Had the blood test now, just waiting on results but I'm really pissed off with that doctor's attitude!
