Should I go to the emergency room?

I've been sick for a few days, at first I thought it was a cold, but now it's progressing into something I don't know.

-I have a fever of 102.2F (I take fever meds, they work and bring the temp down, but it spikes back to 102.2 as soon as the meds are out of my system.)
-I'm constantly cold, no matter how many blankets are on me
-I'm really nauseous
-my nose is stuffy and runny
-I've been sneezing, which makes my lower right abdomen hurt
-I'm constantly waking up extremely gassy (I'm sorry for the TMI, but I wake up in extreme pain from it.)
-I'm able to do a bowel movement, but I feel like I'm going to throw up as I go.
-and I'm extremely weak, and I feel like any movement my bones will break

is this a normal cold, or should I go to Emerg?
