I recently got sunburned on my face and head and used aloe vera gel with lidocaine. after using 5 times why did i feel dazed and confused the next day?

Multiple: If your burn had been severe and extensive, you might not have had enough sleep from the pain-> dazed and confused. If you have using too much lidocaine it can possibly but unlikely numb you as well although you will have to use a huge amount to get any systemic effect. Dr Fowler also raised the question on your hydration status. See doctor if problem persists or recurs
