Migraine + Aura

I am 23 years old.I dont live in any english speaking coutry so please forgive me my poor english.Im currently having problems with migreine with aura.Sometimes suddenly out pf nothing flashes and multicolored lights starts to appearing before my eyes.This takes about 20-30 minutes,after that mild headache will occure.Headache itself isnt realy problem(i is very low pain)but that aura is horrible.Im also have problems with so called visual snow(which I usualy worse for few days after aura atack).I have this problem like 4 years already but in past few days after more 2 months without aura I have several migrene/aura attacks in very short period of time.Any advice what should I do?I visited several doctors in past years(neurologist,eye doctor..) but they didn’t find anything.
