Thanks for writing your query.
takes few days to weeks to recover completely. You should take complete rest. You should avoid watching television and working on computer and text messaging.
Proper rest helps you recover fast.
If you can postpone your trip for few weeks, it will be of help.
You should get a scan of your head done and get examined by a Neurophysician.
I hope this is helpful to you.
If you have furthur query, I will be happy to help.
