I run 6.2 miles every other day and when I started 4 months ago I too shook and shivered as I ran. Get a good compression shirt and pants like that made by Underarmor. It holds all the looseness in place as you run. I did and I love them now. They are skin tight as you can see in the photo below but they make all the difference in the world. Running gets easier as you progress but don't go to fast or you'll get injured. 1 mile to start is too fast. Walk before you run girl.
I had my surgery on April 23rd, 2014 in Tijuana and started walking slowly a month later. that progressed to walking quicker and longer over the next two months until I was walking 10k (6.2 miles) very quickly. I'm Canadian hence the metric crap. We hate it too. At that point I started to run a minute/walk 5. Eventually I could run a mile then two and now the 10k.
Running is all about form I discovered. If you don't employ the right form you will hurt. It takes time to build up stamina. I run outside. Today it was -23 here in Saskatoon but layered up and ran 4 miles of sprints. Crazy Canuck? You bet but I feel great, pain free, and stress reduced.
