I have numbness on the left side of my lips and wonder what that could be. I have a history of a micro adenoma on my pituitary gland which never bothered me. I was followed for several years and after my last mri, was told it was gone. I have had a small amount of lactation and this numbness in my lips and was wondering if this could all somehow be related. I'm scheduled for some bloodwork tomorrow, but would like to know your thoughts.
