Don't know what's going on...

Last Friday I had burning in my stomach (assumed indigestion) Saturday it turned into an actual hurting/soreness. I never take naps but I took a 3-4 hour nap that afternoon and woke up to my ENTIRE body hurting and stiff. Felt that way for about 36hours. Neck and shoulders didn't nstop though. Now, it feels as though my neck is bruised and hurts to barely touch it and my shoulders are so sore and stiff. My arms and hands get tingly and weak at times. Took another 3 hour nap today and woke up feeling like poo. Went to bathroom and my nose started bleeding.. Wtf is going on???
