I've been dealing with nausea the past month when waking up so unfortunately, I can't use that as a symptom. I went to the doctor a couple weeks ago to get checked out but my urine test there was negative. He said that nausea could come from acid reflux, which I have a problem with. He did blood work to check my thyroid and other things but I never heard anything back...which I just realized. I guess I need to call them!! I'm feeling some tiny pings in my stomach and lower abdomen. My lower back hurts, but I stand on my feet a lot at work so that comes into play as well...
