I Have A Migraine Started Three Days Ago Will Subside

I have a migraine started three days ago will subside but with physical activity gets worse to the point where I have to close my eyes and lay down, upset stomach, age 40 with a sinus infection and third day of amoxicillin. Symptoms started with a sore throat, headache, sore throat gone- but head pain at top of scull all the way Down to back of my neck and behind my eyes.. Veries intense to dull annoying pain. (Psudeotumor?)
