Thank you all for your concern for me!
I think I need to give an update on my epilepsy condition, where I am at now with life. I did a bunch of research while I was mostly stuck at home on what causes seizure. I wanted to know more about what might factor into having it, what is known about if you have had one, and what can be done for it. I'm sure there is much more to know then I do, but what I learned helped me to understand why I had them.
The really short answer is that they don't always know why people have seizures, or what causes them. They can't necessarily prove you had one with any cat scans or x-rays or anything unless you have one right then. Mostly people are seen having one, then the exams show that your brain has damages from having one, but they are not always able to tell.
I suffered a head injury as a child that could cause seizure or make me more prone to having them, so that is a possible factor for me. I don't have family history of them or anything that could otherwise explain it biologically. Something very important, though, I found a list on the epilepsy websites about which over-the-counter drugs can cause a seizure reaction. I was never asked by the doctors if I had taken anything such as allergy, cold or flu medicine when my seizures happened. This was very important realization for me because I had taken the drug called Diphenhydramine Hydrochloride and it was working in my body each time I had one of the grand-mal seizures. (The brand name for it is Benadryl.) The number one OTC drug on the list for causing seizure is Diphenhydramine HCL!!! It is used mostly as a sleep aid or as an antihistamine. It is included in most cough/cold/flu medicines that are for night time use as well as many things that include treatment of allergies. You can buy it in generic or name brand pills all by itself especially for your allergies, which I have plenty of.
I talked with my neurologist and he understood about my realization. He included the information in his notes about my epilepsy condition when he had to send my medical information to the Department of Public Safety. The DPS cleared me to go back to driving after my 3 months free of seizure, which only took another 3 months of documents and waiting.
I went back to work after that and so far things are good. I feel confident that it was the drug that was the key because all that time I was waiting to go back to work, I did not take any of the drugs I was given to suppress any seizure I might be prone to having and I never had one. I put them under the counter in the bathroom... I have all these bottles of pills and samples of pills sitting there still, but I never touched them.
I still sometimes feel a feeling that reminds me of how it felt when the symptoms of seizure were just beginning. I can't tell if the symptoms are just sinus pressure changing, stress, maybe my stomach being a little upset like if you take vitamins without enough food, or something bigger to worry about. It has only happened a few times and each time I had taken my vitamins without a lot of food, plus stressful work, so it could just be that. So far my feeling a little strange results in nothing at all so I try to remain alert but not worry too much. I am very careful to check all medications I get to be sure there is no Diphenhydramine in them too.
