Facial and Back numbness

For about a year now, I have had intermittent numbness and tingling in my mid back.  I thought it might be related to my epidural from childbirth, but the docs seem to have ruled that out.  I also have begun experiencing facial numbness and tingling, centering around my nose, cheeks, upper lip and forehead between my eyebrows.  To complicate this weirdness even further, I also have intermittent hand/finger and foot numbness.  Sounds bizarre, doesn't it?  

I am curious as to if anyone else has had any similar problems.  MS and ALS have both been present in my family, but I don't have any of the other major signs of either of those.  Doctors have done a mid/lower back MRI, xray of neck, the normal blood work and the only things that have come back so far are possible muscle spasm in back (wouldn't cause facial numbness) and elevated SED rate.  I'm scared and not sure what to expect - I have an appt. with a neuro consult in a couple of weeks.  Suggestions on questions to ask or what I can expect would be greatly appreciated.  Also, if anyone has any similar stories, I would love to hear about what happened/diagnosis/etc.  Feel kind of alone on this.  My husband has Lyme's but the doc ran a Lyme titer and it came back negative.

Sounds like your going through a similar situation as me. Since April of 2007 I've been experiencing a numbness on the right side of my face. It comes on without warning to a very localized area and then shoots down my right arm but while this is happening my words dont want to come out. I know what I want to say but my mouth wont move. I've been through just about every test out there. They found 2 small lesions on the left side of my brain which they say could be the only explanation. I've seen 3 neuroligists and 2 nuro surgeons and none of them can come up with a 100% explanation. One said brain tumor the other said it couldnt be because the way they are its not common another says MS but the test results come back negative. So I'm kind of placing the waiting game. I go for mris every 3 months but there has been no change. They have me on sesuire medicine but I still experience these espisodes approx. once a month. I'm not sure what to tell you to do but I can just let you know your not alone. Good luck. Connie
