I have a terrible migraine now, which did not subside after taking Paracetamol. Please help.

Hi doctor,

I have a terrible migraine now and I have taken Paracetamol. But it has not subsided even after the tablet before two hours. I am working from home and I sit in front of the computer for nine hours a day for seven days. I need to log out from my shift today as I have terrible pain. I am very sensitive to light and noise. Suddenly I had a blackout with crowning pain in my head and an irritating flat line sound. This happened to my husband last time and I took him to the hospital. They gave him Dextrose. But I am not willing to go to the hospital due to Pandemic. Please help.
