Hi.... My Right Side Of Head Is Sensitive To Heat

Hi....
my right side of head is sensitive to heat and cold and even the right side of whole body. Also, after a continuous work on laptop for a week or so, I get severe headache. this is also happening after a depressive condition. Recently my diet has changed and causing gas and yesterday I had a severe headache which was intolerable and a physician suggested me some migraine related medicine along with antacid and stomach medicine. So can you please diagnose the exact problem.
