I was at the gym and was taking to a nurse. Telling her I was feeling like crap. She said I looked like i was retaining fuilds. She prssed on my thigh and watched how long it took for color to return to skin and then promptly called a Dr she knew. Said something liek it took x # of seconds and I was retaining a ton of fluids. He said I should go to ER - she really emephasized it was important so I did. They did tests and thats when it was discovered.
