Just generally, aside from major health problems that can obviously affect anyone, women can have years of period pain/associated issues/ hormone hell, pregnancy and childbirth then later menopause. It can all cause a lot of pain discomfort and mental health problems. Men do have it easier on the whole don't they?! I think women minimise it a bit too much. It is hidden especially in the work place where you do just have to get on with work despite possibly feeling like crap a disproportionate amount of time!
Just found myself musing on this today as I have my monthly lower back and hip ache to contend with!
