Is it normal for the chords to hurt...?

after you're first day of singing? I mean, i usually sing everyday, but I wasn't singing right. Just today I began singing along with notes on the piano and it opened me up to the real world of singing. Is It normal for your vocal cords to hurt after like the first day? Also, I have been trying for the high notes and the falsetto notes, and when I attempt this, my neck tightens up very much and it's very sore. Is their a way to relax the neck muscles when going into the falsetto notes? Also, if I practice everyday, will my range get better? Cause right now my range is horrible...i can probably sing a little over 1 octave (not counting the falsetto). Im a 20 year old dude, btw
