Uncomfortable in my own skin

I must admit, except for my first trimester migraines and my heart palpitations I have been fairly lucky during this pregnancy.  Up until the last few days, I was relatively comfortable the majority of the time.  Yes, I had basic pregnancy complaints (edema, swelling, constant trips to the bathroom, etc) plus my share of special to me discomforts (see above migraines and heart palpitations) but I was really doing fairly well.  For the last 4 weeks I've been walking between 4-8 miles almost every single day.  I've been cooking and eating healthier for the last 9 months than I have in a long long time.  Unfortunately, now that I am in the final stretch of this pregnancy (4 days to go!!) I am extremely uncomfortable all the time.  I won't bore myself by running through the my list of discomforts because I'm not alone, most women go through this.  But man oh man I just needed to take a moment to complain and say - I'm tired of being uncomfortable.
