I have to wonder why some of us with so many joint pains and neuropathy, that our sed rates arent higher,, I guess that could be why some of us dont get a Dx for so long,, I saw mysterious Diagnosis last night,, this poor girl had had ever increasing abdominal pain,, heart rate went through the roof,, and she was a runner,,, she was pretty much near death before a doctor finnaly figured it out when he asked if her urine was purple,, she had Porphia,, odd part was she got better after each (episode) when she drank sports drinks,,
