Hi sir/madam Thanks for choosing health care magic, I Would certainly understand your concern regarding your experience as it is very disturbing, but i can explain you the unknown fact about the feeling you are experiencing that it is very common in any one , but it occurs mainly when the person is under stress .This is actually an abnormality of memory ie mainly an interplay between short term and long term memory In dejavu, the person feels unfamiliar things familiar and as if he has undergone that situation in the past. so, to get rid of this , I can advise very simple tips like distracting yourself by engaging in some work, you must make up your mind that it is very common , harmless, may occur to anyone. More over, it indicates presence of good memory instead, the other tips are like counting numbers, rubbing your fingers, following some breathing techniques. first of all, reduce your stress, have good sleep and get relaxed. if you are worrying about that continuously that may cause your headache. some psychiatric problems may cause such kind of experience like epilepsy and other, so i would like to know about those conditions if you are suffering with any? like schizophrenia. if you does not feel any relief with the simple tips, you can try with antianxiety drugs like escitalopram . consult your doctor for reassurance post your further questions if any I will be available to take up your follow up questions. thank you
