You need to see a doctor ASAP . As far as driving ,, Ugh ... You have to take into consideration if you cause an accident you could injure or worse anyone on the road. That would be something hard to handle. I black out once went off and embankment and went flying off a 6 foot drop off and hit the ground so hard that jerked me awake. I was so grateful I did not harm anyone but myself.. I got lucky.

See and Doctor and take care of you
