What kind of sickness do I most likely have?

Patient: I have been sick since Thursday and I have been coughing like crazy. Every time I cough my stomach/torso area tightens. I have a loss of appetite and a really funny nose along with sore ears and a massive headache. Also every time o stand up I get dizzy and my legs hurt really bad. I just wanted to know what the possible sicknesses are that I could have.

Symptoms: Symptoms: coughing, sneezing, severe muscle pain, runny nose, hard to breath when I cough
