When I had shingles, at age 35, I thought I had torn something in my lower shoulder. It felt like I had torn a ligament or broken an upper rib. It was no fun.
My Dh had shingles at age of 33. His was around the top of his shoulders. We had no idea what it was at first and our 4 y/o contracted chicken pox from her dad's shingles, then my other 3 got it and unfortunately it ran thru their elementary school. We had no idea that you could spread chicken pox from shingles
