I saw an ENT when the lymph nodes behind my ears were swollen to the size of hazel nuts, however it was brushed off as a reaction to some type of infection and the resulting size was due to scarring. Due to your suggestion, I read up on PMR and found that hardly any of my symptoms match. I am under 25 so it would be an extremely rare experience, but I appreciate your ideas. My symptoms are completely random and never seem to be specific to a certain time. It could be three o'clock and my leg itches, or it could be ten thirty and the joints in my fingers feel like they've been smashed with a hammer. It doesn't surprise me that it's hard to diagnose, but it is disheartening.
