Hi RainbowBrain,

I'm sorry to hear you have been having some medical problems. If I may ask are you taking any prescription meds because if you are and you feel dizzy, lose your balance, or have blurry vision your med may be at a toxic level in which you need to let your Dr. know immediately so they can cut back on the dosage.

I've had brain surgery twice for epilepsy and I'm not a Dr. but it could be that you have a large amount of scar tissue or a possible tumor in the area. Headaches are one of the first things that can happen with tumors along with everything else you described and that's because the brains neurons are firing up causing more problems. Try putting a cold wash cloth on your face and the back of your neck 3 times a day at the same time and anytime you start to get a headache by doing this it will calm the neurons down in your brain, it's called "Cold water therapy" I had this done a few yrs. ago in a medical study and it also reduced my seizures.
My best advice to you is to have your family Dr. refer you to see a neurologist or Epileptologist which is a Dr. that specializes in both neurology and epilepsy. These Drs. can do more detailed testing on you like a SPECT or PET scan to see what's really going on.
In the meantime get a calendar and write down any times you have a headache put down what time it started and stopped and also take note of the weather because often a low pressure in the weather can cause headaches for many people. By keeping track your Dr. may see a pattern in the time of day or night you have any headaches or what days of the month they happen. Cut back on the caffeine and stay away from alcoholic beverages until you know for sure what's going on. You may want to try taking vitamin B12 1000 mcg. once a day because that will help calm the nerves down which may help you with your headaches. I wish you the best of luck and May God Bless You!
