..was just reading, about TOS, on one of the links you sent me. Are you supposed to, for diagnostic purposes, have all the listed symptomology? I never have any kind of chest pain, ear pain, anything like that. How does a doctor differenciate between RSD and TOS, or any alternative condition altogether. Though I will not claim to know tons of info. on RSD, I did read that, what makes it hardest to diagnose is that its symptoms and patient's complaints/descriptions of pain, resemble, very closely, other problems in a variety of areas etc.
