Is it possible to bruise your ribs from profuse vomiting?

I have terrible insurance, and sadly I work for insurance company United Healthcare, so I don't want to spend money on deductible to just have a doctor laugh at me. I vomited 11 times on Sunday, at some points so hard that I couldn't move out of bed, so then next day I was weak and my ribs are sore on both sides. My grandkids got over there flu bug faster, but then vomiting again today. I am nausaus, but careful not to eat too much, just saltine crackers and sipping white soda. But just breathing deeply hurts, and laughing is really painful. Just sitting upright even hurts after an hour or so. I've thrown up plenty in my life, but never had this happen before.
