Head pressure and pain (w/ dizziness and lightheaded at times).

I am a male, 21, use to drink on holidays, have not drank for a year, and do not smoke, but parents do and I live with them.

I have had head pressure and some day it is bearable but lately it has been unbearable, sleep helps, only because I am sleeping and cannot feel the pain. Also, when I put pressure on my neck or lay down my head does feel as if it is getting better; could this head pain be part of a neck issue? Some days I do feel dizzy and lightheaded because of this head pressure, at least I think it is from the head pressure, when I do get lightheaded and/or dizzy the pressure is there. The head pressure and pain is usually located around my eyes, ears, temples, and either only on the right side (kind of on top) or on the left side (also kind of on top), never on both sides at the same time.

I know you are only for head problems, but I was hoping you could help with the fact that sometimes either my heart or below my heart hurts, a slight pain, not constant at all, occurs. It always goes away but I feel as if anything around the heart is too dangerous to ignore. This pain only happens on the left side of my chest about a thumbs length below my left nipple.

Thank you for you time in reading this, and I hope you get back to me soon.
