i woke up this morning with a sore head ,, felt like id been hit with a hammer right at the top center (slightly to the left had side) of my head. .. i then noticed the pain only comes every time i breath in through my nose , i have been awake since 10am this morning and it is 16.05 now .. it is still hurting ,, my girlfriend told me i banged my head in my sleep so loud it woke her up .. i dont remember a thing ? it feels like somebody is pushing a thumb into a bad bruise everytime i inhaler through my nose.. should i be concerned ? .. i hope it stops soon
