I got bent once and did not realize it until two weeks after the fact due to an overlying back injury from a fairly recent car accident. I attributed the post dive numbness and tingling in my thigh to overuse of my not yet fullly recovered lower back injury on my first post accident dive. When I saw my Dr. two weeks later for a follow up visit, he was initially confused as those reported symptoms (now reduced to some numbness on the surface of my leg) had no neurological connection to the site of my back injury. After an interview discussing my activites and a in particular a particular dive profile, DCS was identified as the probable cause.
In my non medical opinion, I'd suspect the opposite in your case - the symptoms are probably due to something other than DCS as the probability of first encountering symptoms of DCS after 48 hours are very, very low.
