Feel tired all the time and my muscles ache? I have headaches and my back and upper forearms hurt bad
There are so many possibilities based just on the symptoms you've given us...
Carbon monoxide poisoning
Chronic Fatigue Syndrome
..I think this requires a trip to the doctor - we can't diagnose you.
Well I have the same problems but it's caused by my not sleeping and the fact that I play soccer everyday and weight lifting but see a doctor that's how I found why I felt this way.
Are you getting a full nights rest? Not sleeping and getting you full REM sleep (reparing sleep) can cause all of those symptoms.
