severe headache for 3 days getting worse

i’ve been to the doctor so much in the last 6 months as i am constantly sick, i just moved to the UK 6 months ago and i’ve not been well since, i worry i’m being dramatic, but i’m in so much pain. i have a lot of facial pressure and a throbbing headache that is constant. i’ve currently been sick with a virus for two weeks. went to GP last week and he prescribed antibiotics but advised not to go get them for another week just to see if i got worse. my husband is going to get them now. it feels like A&E levels of pain but i don’t want to me dramatic. my eyes are also very swollen and watery. i keep avoiding coughing because it shoes more pain in my head but my body keeps needing to.
