My 16 year old daughter has for the last 4 months had what we now believe to be quite debilitating headaches just before her period, we have been keeping a track of them and they happen a few days before her period starts, paracetamol just doesn’t touch them, all that seems to work is to go back to bed for 2 days, which obviously is not practical. I’m going to take her to the gp, but would like as much advice before hand, I’m thinking the pill but not sure how that works to prevent head aches, any advice gratefully received.
