PD going her way Steve!
I had the same thing years ago, it started the same way , rough patch in the middle of my back really painful , it usually follows the path of a nerve, in my case it went all around my waist. It was very uncomfortable. I was out of work for a week originally , but because of my job requiring me to wear stockings and I couldn't have anything so tight around my waist, my employer would not let me go to work with just knee highs and a dress , even after the doctor called them up and asked them , so he took me out of work for a month.
There was no medication for them at the time, I had to let it run its course , I will never forget.
DD1 also did have the shingles 2 years ago, but she did get meds and her case was much easier.
BTW, I was told by the doctor, you CAN get them again and again, it doesn't happen too often but the disease stays dormid for the majority of the people , but sometimes it reacts again.
