I would think that the extra salt could make the blood vessels dilate, which could actually end up exacerbating the problem. Have you had an MRI or an MRA? It may show if something is pressing on the nerve.
Interesting. I'll have to pay attention to this particular problem with salt/fluid to see if I notice a change. Even if I do though, the other stuff way outweighs it in magnitude and I'm 100% positive of the connection with that. It's predictable and it happens when I'm not paying attention to it. This one, being a smaller issue, I don't usually pay attention to - only when it hurts and even then, mostly when I'm not kept busy with other "brain exercising" things. General unloved, mindless busywork (like housework) sure doesn't help.
MRIs, yes. It's how they keep track of the brain tumor I have, though it's been a couple years now (I think) since the last one. That tumor is fixed and just on "watch" mode.
MRA? Fancy you should ask. It's what I thought would happen (seemed rather obvious with symptoms actually) and specifically asked for due to hearing my pulse and nothing showing up on the MRI (which was a good thing, because another tumor was what was originally suspected!). I was told there was no need - and this at Johns Hopkins, so hardly a small local hospital without much experience. Money was not an issue. It's merely their lack of belief that these things are going on. ("Try to reduce stress!") My guess is it's too rare except when with the "right" specialist and if one can't get past the gatekeeper to get a referral, one can't get to the right specialist. I can't "fix" that.
Well... 'tis my hope with middle son in med school still. I don't have to convince him. He just needs to gain more information, then contacts who will take his word for it (since he can't actually investigate himself due to our relationship).
It seems it's pretty common for doctors to disbelieve things they can't see, esp when the "most likely" cause doesn't turn up in a test, but even without that. I went to an ENT (twice - their insistence) to check to be sure it's not an ear issue. The first one took one look at my chart and casually mentioned my vision issues due to the brain tumor outright stating, "I don't see any problem with your vision looking at you." I'll admit I wasn't quite sure how to respond - it wasn't even what I was there to see him for. My mind was just glad the first eye doctor I went to see didn't say that. At JH, plenty of med school students were brought in to see what to look for, but I suppose as the years progress they don't actually see it and forget?
Then too, I've seen several folks at the hospital now (usually with my mom, but some with my own things) and I "get" why stress is an issue. It'd be my first guess too with many folks I've just casually seen - not knowing who they are.
It's all part of why I chose to back out of even trying to continue to pursue getting that stuff fixed. It's very much a "not likely to win" situation and that is what causes me stress. It's easier for my body just to figure out how to deal with the issues than it is to deal with others in charge who aren't going to believe what I say anyway.
At this point I'm only going to see a doctor about things that are 100% obvious to everyone, or close to it.
Even that doesn't always work. I have painful lumps under my left armpit that literally just appeared two years ago now. They were investigated and a mammogram + ultrasound found nothing of concern (a good thing). So... I was told they've always been there and aren't an issue. I can believe they aren't an issue (aside from the pain I put up with), but no, both hubby and I know they haven't always been there and the pain they caused at the beginning (much more intense than what's there now) let me know exactly when they appeared. It would actually fit into the abnormal blood vessels growing/appearing theory - and that one is known to have happened with a lump removed from my finger - plus I have a vein in my hand that anyone can feel the pulse in - another thing that came on ONE day (at least, one day of intense pain from it when it started).
In my mind there's a good possibility it's all connected. What happened in the hand could happen elsewhere and not show up on the tests they did. In their mind I'm a stressed out wacko with weird theories. I'll admit my theory might not be correct, but it sure seems to fit what I KNOW is there and to me, would be worth checking for. It's not to them. They get to call the shots.
That's the total impasse in case you were curious. Well, I know I've left out more details here and there, but that's a summary. It's a long enough post anyway and getting off topic.
