to nurse nancy- I don't now about the o bands,but I know with the spinal tap I had 14 cells when I should have had 9.At first the dr thought I had guillian buirre(ooh,the spelling lol),but after the mri's it was pretty clear that it was ms.I am pretty lost at this point because I am just now seeing a dr at a volunteer program,they are supposed to hook me up with the right people(fingers crossed).so am staying optomistic just want to get the right info and make a decision,am doing my research,and asking lots of questions.I do find that the more I research,the more scared I get.Thank god for my mom/boyfriend/family&friends!And this site has been such a godsend! Also what is LDN? thanks!
