Fatigue: The list of things that can cause fatigue would fill this room. You need blood work. It could be anemia, or a thyroid issue. Or, you could have an infection you are unaware of. In addition, oftentimes, fatigue is a symptom of depression, or you may think you are getting quality sleep at night, but are not due to some form of apnea.

Only in AM?: There could a medical issue, new mattress or bad mattress?, sleep apnea? Depression? Question a bit vague, once you get going in am do symptoms improve?

Soreness: Soreness in the morning is a concern. Do you have a very physical job - or started one recently that is? Do the muscles ache - and if so where? How long has this gone on? Do you kick, toss/turn, and jerk throughout the night? Snore? Are you taking narcotics? They may wear off leaving you in worse pain or sore in am. A thorough medical evaluation would likley provide answers as to cause and relief.
