Hello Derg...and welcome to healingwell. I am sorry you are feeling so bad.
As Red said, I would personally go to the ER, as it isn't normal to not be able to swallow liquid.
Also, you do not want to dehydrate, as that could be a dangerous situation. The fact that you are feeling faint, and lightheaded is from lack of nutrients going to your body. That is to be expected when you aren't eating or drinking.
I would suggest calling your family doctor, and seeing if you can get a same day appointment, and if you cannot, then head to the ER. You need to get this figured out before it gets to serious.
Something isn't right here.
Wishing you the best...and please, keep us posted as to how you are doing!
Stick around, cuz this is a great place for information, and support!
