I find it very difficult to get the balance in terms of how strongly to emphasise personal concerns. A friend told me off a couple of years back for downplaying a health problem when talking to health professionals, but leaving aside my upbringing, I'm always anxious about being written off as 'hysterical female'.
I think there's an art to emphasising what the problem is in a way that avoids stereotypes and gets the message across. I wish I were better at it. Something like "I'm sorry to have left it a while before seeing you, but obviously I didn't want to waste your time. The problem hasn't gone away, though, and I've had time to notice some things..." But better phrased and adapted to relevant condition and relevant doctor/patient relationship.
I got round it with one issue (to do with spasticity) by drawing up a table with all the relevant info in it and printing it out, which, with my explanation of there being lots of factors I considered relevant but my being aware that I can be longwinded verbally, worked a treat.
I had a very close friend who, years ago, had pain in her chest. She saw the GP, who wasn't incompetent or uncaring, and who gave an initial diagnosis of indigestion. She then had a cardiac arrest. She was resuscitated and used the experience to warn others to seek help earlier and to go back if a preliminary diagnosis and treatment don't work.
I look back over my life at how often bad experiences with health professionals has deterred me from being assertive, all made worse by societal stereotypes.
So daft, because it's actually wasting NHS time and resources not to be assertive and get into the system soon. Incidentally, it's easy with long waiting lists to wonder if you're unfairly jumping the queue if you seek help now, but how much more does it take in the way of resources if you wait to join the queue and get worse?
That being said, I suppose you could call me a hypocrite, because my GP diagnosed a condition and referred me to secondary care. A doctor there examined me and told me that my GP and I were wrong about what we could see. No, we're not. But I can't cope psychologically with pursuing the matter at the moment, it won't kill me, it's uncomfortable not painful, and in due course I'll go private, preferably overseas.
It would be a different matter if it were something I needed to be more careful with.
