Is my guinea pig dying? URGENT

Question
Hello. I am in dire need of help. It is an emergency. As of late i have been unable to afford pet care and I need to know how to help my poor guinea pig. A couple days ago I noticed that his pellets and water were untouched so I put some hay and lettuce in his cage and he didn't run to eat them like he usually does, he just left them there. Now he is shaky and it seems like it pains him to move. I tried to force the water bottle tip into his mouth and make him drink but it seemed like he either didn't want water or he couldn't open his mouth. I also noticed within the past day or so he was developed a slight wheeze and a discharge out of his nose but no discharge from his eyes. He also doesn't seem to be defecating at all. Please please help me help him. Is there anything I can do?

Answer
I'm so sorry Nicole. This poor guy is gravely ill. Typically the shakiness and pain with moving is a sign of impending doom.  Forcing water in him is not wise as it may cause him to aspirate and get some of the water into his lungs. Once that happens there is little you can do. It will cause what we call aspiration pneumonia.

I fear that I'm probably already too late to help you, and I'm so sorry I can't give you something more positive to hang onto.
