Pain in upper right quadrant of stomach.

Since two days now i have a pain in the upper right quadrant of my stomach just below the rib cage. This pain is starting in the morning, it's so strong that it's waking me up. I can't go back to sleep until this pain will go away (today it was almost 1 hour, yesterday it was around half an hour). When i suffer from this pain i feel bloated and full like I've just eaten some heavy meal. During this pain I also suffer from heartburn and I'm belching a lot. Pain intensifies when I'm pressing that part of stomach with my hand (even gently). This pain in it's peak is also going to my back. Today I've got also nausea and just a bit of dizziness. Other things: No assumed position will ease the pain. I didn't took any painkillers as this pain is going away on it's own after some time and then during the day I don't feel any symptoms (except maybe heartburn that comes and goes during the day but then again I suffered from heartburn before).
