PLEASE HELP!! NEW DISCUS OWNER!!

Hi, I have 6 3-inch discus in a 40 gallons tank. Recently, the pigeon blood discus started to have a few white dots on the body, but now that they disappear there are like 5-6 worm-like dots surrounding the eye area. Tonight, I also noticed that it might also have pop-eye too. Any medication or treatment methods?!?!

Really appreciate any help!!
