I hope everyone had a Merry Christmas and a Happy beginning to 2014. I did. It has had its ups and downs but mostly it has been good. 
However, I am in freak out mode right now and need support and prayers on my side.  I had a cold a few weeks ago and had a cough, it lasted a week and a half and then I noticed a bump on the bottom of my left rib.  I examined my rib cage and compared it to the other side and it just didnt look the same, I struggled with should I go to the doctor or am I just being anxious but I bit the bullet and went to the doctor.  It only hurt when I played around with it (palpated it) but I thought maybe I cracked a rib coughing. So I went to the doctors Wednesday she examined me and said "it could be a soft tissue injury or possible a fracture" I was ordered an ultrasound and an xray.  So yesterday I went to have them both done.  I came home and they called about my ultrasound and told me that I have an 8mm cyst on my left kidney.  I am awaiting an ok from my insurance to have an MRI done and will find out monday.  I was so upset I called off work for the first time ever.  I dont know how to feel on one hand it could be nothing but on the other it could be something, and I still dont know what is wrong with my rib, I was so shook up I didnt ask if it was what caused the now pain I have on my left side.  
I just needed to get this off my chest and I know that I could just be tweking about nothing but anxiety does this to a person.  I keep thinking I have cancer or something and just need some support thank you.
