Watch the amount of salt your are eating as well.
You need to ask for a referral to a Nephrologist.
I wouldn't get all freaked out yet because you don't know exactly what is going on. Do follow up with this.
Meanwhile avoid alcohol, smoking, ibuprofen, caffeine and drink plenty of water. Get exercise on board and clean the junk out of your diet.
Again, get to a Nephrologist as soon as possible.
