Sounds like a good plan, Denis. An open mind is a great policy. I know it's much easier said than done, but try to let your mind relax this weekend. You have a great plan in place and you deserve a nice couple of days to rest up ahead of your appointments.
If you don't get to see your GP too often, it can be helpful to write down your questions ahead of time. Those appointments can pass by in a flash and most of us know what it's like to remember a bit too late what we meant to ask about!
Hi Denis! There aren't too many of us on here from Ireland, so it's a nice surprise.
First off, please don't discount those sharp chest pains or lump them in with anything else. Have you been looked at for any cardiac conditions? Whether or not they're related to the other things you mentioned, I'd strongly recommend you have them assessed if only because these can be related to heart health. It's just good for all of us to stay on top of those possible issues.
I also have a background involving stays in hospital for mental health reasons. I didn't find them a hinderance in being referred for neurological services, but that may be because my first MS presentations were pretty unmistakable.
Nothing that you're mentioning seems to say "MS" to me. Because MS can affect so many different parts of the body, it's extremely common to have it come up when looking at symptoms on the internet. It can be counter-productive to state what you think you have to a physician. This is because it indicates the patient might be engaging in cognitive bias based on things they've read and (consciously or subconsciously) making their experiences fit.
It's usually more productive to say "I'm experiencing the following. It's negatively impacting my life and causing me concern. What are your suggestions in this situation?" I'm not sure if you have private insurance or use the HSE, but this doesn't always get the ball rolling on the first try. Don't be shy about pushing back a little if you feel your GP is not addressing your experiences. This doesn't mean they necessarily have to agree with you on everything, but they should at the very least offer some possible reasons for your experiences, offer symptomatic relief, and some sort of short/medium term game plan.
To be honest, as services and general GP awareness can vary so wildly in Ireland, some of it can depend on where you are. My experience here in Dublin has been overall very positive.
