Sounds like part of your problem might be a migraine if you are sensitive to noise. Try taking anti-inflammatories (like ibuprofen) and follow the recommended dosing, being sure to take more after the appropriate amount of time. Also, drink LOTS of water. Headaches can be triggered by many things, but the one most common for me is dehydration. Maybe even try Gatorade or other beverages with electrolytes. Be careful of your caffeine intake. Drinking more or less caffeine that usual can also cause headaches. If you have any sinus congestion, that could also cause a headache. Take a decongestant if you have any congestion.
The body aches could indicate that you're fighting something - either viral or bacterial. The ibuprofen should also help with the aches and any fever you might have. If this continues after 24 hours of ibuprofen, you should probably make an appointment to see you doctor.
