I had the same problems. With me, it ended up being mitral valve prolapse, sounds bad and like it's a heart problem, but it's really not. It's a blood volume problem, so basically you are dehydrated. Your body tries to compensate in all sorts of ways, by making your heart go faster, by producing hormones to make it go faster (this results in the marks, one of the hormones is extra cortisol, that causes that). Basically, you're dehydrated because you don't have enough electrolytes, so your body compensates by releasing more water, so the electrolytes you do have won't be as diluted. So, the solution for me was to take in more salt (use sea salt since it's got a mix of electrolytes in proper balance rather than just sodium). I just mix some in to my water occassionally, especially if I feel like anything's starting to go numb. Has fixed all my problems, amazingly. You can't hydrate yourself just by taking in water if this is the problem, your kidneys are just going to immediately release it. You need the extra electrolytes to tell your kidneys to hold on to the water (it's all about the balance of water and electrolytes).
I tried a lot of things before this, and this is what finally worked, and it was so simple and cheap. I was glad I finally found the answer, but a little mad that I had spent so much time and money before on things that were totally unnecessary.
