CC... maybe its medical, and the replies here have me wondering... but when I had read your post only I immediately thought "lactate threshold". You say this happens during strenuous activity like climbing on a bike... thats inevitably when my HR spikes.
I can't comment on the hiking as it is years since I have.
When you get to LT, your heart rate is way up there and you can feel a combination of dizzy, headachey, sore legs/abdomen, and thinking about/wanting to throw up. When my HR is way over lactic, not only do I feel like I am going to be sick, I also begin to believe my heart my just burst up my throat and crash into my skull.
When you ease the exertion, the lactic acid begins to disperse and things start to feel better and more normal again...
When the intensity is intense you get these symptoms... a Heart rate monitor would help to identify this. Veronica asked... do you have one?

Courage does not always roar. Sometimes, it is the quiet voice at the end of the day saying,
"I will try again tomorrow".
