What Causes Severe Fatigue And Pain In The Joints?

I have been progressively sick starting at the beginning of last weekend. I was feeling excessively tired, but I blew it off due to a couple of other non-medical issues I was dealing with. the tiredness got worse, then the pain started. I had pain in my bones, muscles, joints, and skin. it got so bad that I couldn t move well at all. I didn t eat for several days because I just didn t have the inclination or energy to do so. I slept three days straight. I have had excessive sweating, even now the sweat is rolling off of me. last night I began with stomach issues. pain, liquid b/m, very strong odor. I have not felt sick like this before, not sure if it s bacterial, viral, or something else entirely. I feel poisoned, but I ve already ruled out food poisoning
