Viral with muscular: Given your generalized symptoms, high suspicion and concern for a viral upper respiratory/sinus process with secondary muscular tightness. If symptoms continue during the day, fever present, loss appetite and energy more suggestion toward systemic viral origin. Even thought back pain can be severe at times, fact that not constant, nor radiating pain, less likely originating from the spine.
