Suggest Treatmenrt Severe Headaches During Pregnancy

i am 25 years old and 26 weeks pregnant. i have suffered with a severe headache/pain in my forehead and into my right eye for the past few days. my eyelid is drooping down. i was admitted to hospital on weds night and a decision was made not to give me a ct scan due to my pregnancy i was given tramadol regularly for the pain but it didnt seem to help at all. i became very frustrated and discharged myself from hospital yesterday morning.
