i am so sorry you went through all that.... I have symptoms of arachnoiditis, I just found out about this disease so I dont know much about it, other than it can be caused from myelograms as well as steroid injections using depo-medrol...Im talking to my dr about it fri... and sorry it is frustrating when drs dont know whats going on so they dont believe you or think you are not in as much pain as you are describing... good luck, I hope things get a little better for you!
