Took a pill and i need to know exactly what it was.?

I went to a party last night and I took a pill, it was dark dark orange with a black smiley face on it, and I don't believe it was ecstasy only because I don't have the symptoms of it, my symptoms are sore sore body blurry vision and during the time I blacked out for a total of 4 hours. And yet I get flash backs of what happened but only little at a time. And my body is still very sore head is pounding and blurry vision. Someone help me please!
