I have read that the normal potassium range is between 3 to 5 Emq/L, so it sounds like your potassium level is only mildly elevated. Apparently, it can be caused by certain antiobiotics or NSAIDS. That's best case scenario. An extremely high level is a medical emergency, because it can affect the rhythm of the heart.
Make sure to tell your doctor if you are having heart palpitations and/or muscle weakness. And please keep us updated!
Take good care!
