I have had a headache for three consecutive days i have not had any head trauma the pain is made worse by movement and coughing. is this serious?

See your physician: There are many types of headaches, including migraines, cough, cluster, occipital neuralgia, muscle strain, etc. Keep a log of the timing, duration, severity, and location of your headaches. Also try to identify any headache "triggers" (stress, not sleeping/eating). Take this information to your physician -- three consecutive days is a long time. http://www.nlm.nih.gov/medlineplus/headache.html
