Hello, two days ago I had eaten some bad food and got food poisoning and went to the emergency room. I am still nauseous, which I assume is normal, but my main concern is when I breathe. I can take short shallow breaths, but can not breathe very deep due to a stabbing pain on the right side of my neck that radiates downward into my lower abdomen. Is it possible I strained muscles from vomiting so frequently and violently , dry heaving, and hyperventilating from the pain?
