A member asked:

Increased heart rate for past couple of days and feeling tired, what could be causing this?

Something's up: Perhaps you have little "bug?" a viral syndrome could cause both. If it doesn't resolve with rest over the next few days, it would be worthwhile to be checked out. For instance, anemia from any cause could cause both symptoms. There are many other possibilities if you're not improving.
