Hi, I'm new to this, but I've been experiencing back and leg problems that lead me to believe I may have Arachnoiditis. I've never heard of this disease before, but after several tests - MRI, EMG, CT Scan - the source of my problems remains a mystery. So, I went onto WebMD (mistake?), entered my symptoms, and came upon this disease. From what the tests have revealed, I don't have Scatica or whatever, so this seems to be the only possibility. Any suggestions? What causes this? Are there any meds known to contribute to it? Any help would be most appreciated. Thanks!
