My 7 year old son had a headache that made him cry on 30/01/2022 and is still having them now. Don't always make him cry, Calpol stops them, has been sick a few times. I am under the hosp awaiting a scan but going out my mind thinking the worst. Has anybody experienced this? Came on so suddenly and have not gone away. Doesn't have them all day, doesn't always need medicine. Out of 19 days been sick on 6 days and only had 3 days with no headache.
