Its hard to be sure what the problem is, as we don't have your full medical history. Im not a doctor. Having read your post, I urge you to forget about 2 days time and the interview. The symptoms warrant a visit to the ER without delay. Please don't ignore it. It will probably settle, but its far too risky to be leaving this to chance. I don't want to scare you, but you need it checked out.. I advise the Doctor now or the Er . I understand about the job fears you have, but this takes precedence over that . Keep us posted
Not to scare you, but it could have been a mini stroke or a stroke. You should go to the ER if you haven't already. Thome symptoms you're describing are symptoms of a stroke. Sometimes other things cause those symptoms, so it's important to be assess by a doctor. I wish you the best, take care of yourself.
