Antidepressants Questions??????

Here again.  Hope everyone isn't getting sick of my posts!!  Don't really have anyone to talk to right now either since my hubby has been gone.  Anyways I've been trying to put together a timeline as well, and when doing so I realized that my symptoms started about a month to a month and a half after starting the antidepressant Lexapro.  I started it for postpartum depression.  Anyways this may sound stupid, but I was curious if my symptoms could be any side effects of the Lexapro.  Probably not, but just thought to ask anyways.  Also someone mentioned that sometimes after having a spinal  (as I did for my Csection)  can sometimes produce similar symptoms such as pins and needles, pain and numbness.  I had a horrible headache a couple of days following the birth of my daughter, but it subsided, but then when all my neuro symptoms started I had a deatly headache for about a week straight. It is gone now.  I'm just trying to put some peices together before I go to see another neuro.  OH and one more thing,  I was outside it the death heat of the day mowing our yard and had no worsening of symptoms.  Do MS'ers always have the heat intolerance??  
  Thank you all for your support and friendship.  I really appreciate it.
  God bless,
