i had surgury just over a month ago, I was operated on in the morning and released the same day, (thats the NHS for ya) i had slight pain the same night but the morphine helped, i woke up the next day expecting agony but had no pain. i was tender to touch but was ok. i had slight nose bleeds for a week but was pain free......THEN on week two i woke in the night with agony headache that spread to my face, it felt like my sinuses had inflated and was gonna pop, once a day since then i have had the headaches and face ache. it is only the once a day and only for no longer than an hour but that hour is hell. the doctor said i was normal and will settle but that WAS and IS painfull.
