Pain and Weakness in Hands

I am a 27 year old female with two children and a history of fibromyalgia and degenerative joint disease of the lumbar spine.  Lately since I gave birth to my son in October of 2007 I have been having trouble gripping objects due to pain and the fact that my hand just stops working and I end up dropping items. They also spaz up and I can't move them out of this position for about 5-10mins at a time. This is not something that has ever happened to me before and seems to be getting gradually worse.  I also have numbness in my first three toes on my right foot as well as severe back pain in my right middle side.  Not sure if this is related to the Fibro or if its something else.  I've always wondered if I was diagnosed correctly with fibro or not.  I tend to always have a very elevated white blood cell count ie Leukocytosis unkown etiology.  My vision is getting poor and my face looks like a cherry tomato on my cheeks and forehead which isn't normal for me.  Should I see a neurologist or just get checked out by my regular doctor??  Any ideas what it could be?
