First I get neck pain, then my head hurts, hot sweats, dirreahea, nausea, vomiting flem, cold sweats. I get a lot of sinus drainage. Had my sinuses check and their okay. My doctor says sinus. The hospital says migrains. This started when I was thirty. Now I'm 47 and still dealing with it. My daughter turned thirty and she gets sick now with the same issues along with my sister but hers isn't as bad.
