Hello! The clear fluid can sometimes be CSF I think. I am not sure how to be certain. I would guess if it is clear and thin and there are no indications of allergies. I hope you feel better and find a Dr to help you soon!
I know my resting heart rate is extremely variable. It can be anywhere from 58-135 usually. I would say my average resting heart rate is 90-115. As far as during what I call attacks my heart rate has been as low as 24 and as high as 250. This is certainly no fun. I can probably list 30 symptoms or so that I have.
Again, I hope you get relief soon!
