Yesterday I fainted in the kitchen and fell back and hit my head on the hard wood floor. It took about 5-10 seconds for my husband to wake me. I was very dizzy and nauseous for 6-8 hrs after. I am still having some dizzy spells when I get up from sitting or from standing to sitting or when looking up for a minute or two. I am having just slight nausea. I also woke in the middle of the night noticing front rib pain under my left breast, it feels like its bruised, but I woke up laying on my back and I'm pretty sure I only fell on my back. The rib area hurts when I sit up, cough, laugh ..those types of things. I plan to make an appt. with my pcp tomorrow. Is this something that can wait?
