I would say that every time I get sick (like a cold/flue, stomach flue or similar), which is often now in pre-school years with toddlers, I get back/hip pain. Why is that? Any ideas people? Is it my perfectionism? Like I´m counting on myself to perform at work and in private, then a sickness cripple me and I have to stay at home and rest? I know I´m feeling like I´m not doing what I should when I miss several days of work in a row (which is crazy logically, but still...).
