i have had a migraine for seven days now. i have some numbness on my left side. i was diagnosed with a sinus infection and have been taking amoxicillin for 6 days now with no improvement. i feel groggy and tired all the time. and very irritable. any kind of noise, stress makes it worse. i have tried taking darvocett, maxalt, excederin migraine and none of these are working. I had a CT scan and thats where they found the sinus infection. Could there be any underlying problems for the persistant migraines. It is keepin me away from work. I am normally a very healthy person who does not take any medicines. what should I do.
