Rachel...You also mentioned before that you were having tachycardia...That is also a symptom of endocarditis...

The best thing to do is just go to the hospital...Tell them that you've been having a rapid heartbeat, fever on and off with a past kidney infection, breathing problems, and then show them your nails...The bleeding under the nails is definately a sign of heart trouble...I have a book about illnesses that show up in the nails and that symptom is very specific to heart problems...

Please take care!
