Hi welcome though sorry about your pain. A few questions in the past years anything that you may have not thought of as weird but now looking back could of been a symptom? Like for myself I had very tight calves a year before I was dx and in horrible pain. I have RSD and PN.Also were you sick in the past,drugs or drinking issues? You may want to read on RSD. I have my RSD not from an injury or accident and though less common to develop it like that it can happen. At first I did think I was injured because I was active pre all this. You stated you had basic bloodwork but what about extensive for auto immune conditions or other things like B levels?Before I got my dx I was also suggest Tarsal Tunnel and they even talked about doing that surgery. I am so glad I did not cause it would of made things even worse then the current and even if you have TTS it is one of the last things you want to do. Are you on any meds? I hope you get some answers and relief.
