Lakitu.....first things first......are you jaundiced?
If the answer is "No" then don't worry BUT if the answer is "YES" which I doubt, then start to be anxious.
The data that you have given is insufficient to give an accurate diagnosis BUT:
From what you have said it could well be Hepatitis A, B or C or even Glandular fever and all of these may in the main (without jaundice) are usually mild and self limiting.
So no big deal there.
Now ..ectopic heart beats..... depending upon which part of the heart is producing them, usually harmless and do not need treatment.
So....to sum.............no big deal.
