I can't tell what it feels like. So, I won't vote.
For my legs - I guess I could say that it's like a real bad toothache.
My feet and knees are burning (or freezing - it depends)
I have a real bad backache - the normal type
Excruciating pain in my neck and head.
Abdominal pain is like menstrual pain (but guys would not know that)
Earache, sore throat, migraines.
I could keep going.
