Your handbag may be causing you neck, shoulder and back pain. Especially those over-sized and over-weight handbags that we use to hold the kitchen sink. However, when you start to load these bags up with purses, phones, keys, laptops, water bottle, books, etc., you could be heading for trouble! The average weight of a ladies handbag is around 3-4 kgs. If you carried a 3-4 kg dumbbell over your shoulder for 2-3 hours a day, imagine how you’d feel?
