My son feels dizzy every day and headaches ...

For over 1 year my son, who is now 11 years old, feels dizzy every day and headaches, has pale tremor in his hands and dizziness, there is a lot of insomnia. I've already taken it to the neurologist, we've changed the medications, got a little better, and then prevented him from doing his normal activities, what to do?
Expert answer:

Take him to a homeopathic doctor or psychiatrist, go back to the neurologist and tell him that the treatment did not help, is also an option.
