I'm going to recommend some medical tests based on your symptoms. First, you need to do some blood tests, such as the CBC, to check your overall blood health. You also need to take a self-synthetic image (EEG) to see if it's a tumor. Finally, you can do an EEG to measure the abnormal brain activity that causes seizures.
Doctor, I have a seizure, and I have a little tumor on my skin, and I'm worried about my health.
