I Was Diagnosed With A Benign Cyst In The Left

I was diagnosed with a benign cyst in the left side of my neck in the back below the hairline, i had a xray done of it, so it turned out to be benign, so therefore the Hospital said no surgery required, but i always felt like pressure from that side pushing against my neck/nerves is that possible? its right under the skin the lump i have. Im not worried about cancer as far as right now im just curious is this Cyst thing or whatever could it possibly be pushing against my neck giving me pressure and sometimes pain a bit?
