Kneed in upper left abdomen 3 days ago, still tender mild nausea & lightheaded. worried its my spleen . no insurance. should i be worried?

Yes could be spleen: You need to get this evaluated. What what types of a evaluation are available You may need a CT of the abdomen . There are companies like American health imaging that will do the imaging at a much lower price with your negotiation and without insurance. You can also negotiate with general programs and see what price you can get. It’s all a negotiation.
