I had been having chronic pain in my shoulders and trapezius muscles till one day I decided perhaps it was due to lugging groceries from the supermarket.
So I ordered a backpack from Amazon, and ever since I’ve been using it, the pain has been gradually disappearing.
One of the best investments I’ve ever made.
