Can GPs be trusted?

Given my recent history, you'd have thought they'd have paid a bit more attention to my (apparent) water infection.  In transpires I didn't have (never had) one - it's a manifestation of my (recently grown) tumour.  So rather than being another month down the line with little action, I could have finished my first cycle of chemotherapy now.

Perhaps I shouldn't be too judgemental, and some (a lot?) of the blame here should go on my shoulders.  However if your supposed to be a doctor, then perhaps you should read the patient notes and come to an informed opinion, rather than assume some ache/pain is just normal...
