I am sorry you are going through this...You should request an LP for sure. Mine didn't hurt at all. I know people have different experiences but mine really did not hurt. And at least in my case, even though I had lesions, symptoms, an attack, AND a positive LP (4-obands) I still didnt get a diagnosis. I got a "most probably MS" but thats it...no meds no nothing. Then my second set of MRI's showed new lesions plus a cervical spine MRI showed inflammation also. THEN I was diagnosed...Depends on the doctor.. But to be honest with you, I wouldnt have started meds if I didnt have a change in lesions...I am not someone who wants to medicate myself without knowing 100%...as difficult as it is, you are better off not taking such intense meds if there is no definite reason to... (That is MY opinion but others differ..) I only went through it for 5 months and it was so tough...2 years must be crazy!!! Look for another good doc if need be. I found my doctor on the National MS website and referred to the chapter in my area...
Usually a week is what everyone is telling me here. My first LP info result or lack there of was within about 8 days, including a holiday and weekend. But the neuro's office did tell me U of M is pretty slow and they have been known to take a couple weeks. I live in a rural area so the spinal fluid gets sent to the University of Michigan from our local hospital. I'm giving them until this Friday and then I'm going to start becoming the squeaky wheel. I've went through all the possible scenario's in my mind a million times, I just need to know now.
Hopefully your results will come sooner.
