Hi Lee,
Welcome to the forum! I'm no neurologist but I've had epilepsy for 38 yrs. and what you are discribing sounds like you might be having a simple partial seizure also known as an aura seizure that is leading into a either a absence or complex partial seizure.
Stess and lack of sleep are the 2 main things that can trigger a seizure along with hormones changing. My advice to you is to get a calendar and write down what time these possible seizures happen along with a discription also write down when you stop and start your monthly cycle. By doing this your neurologist may see a pattern in your seizures. I would also advice you to go to an Epilepsy Center and see an Epileptologist (Dr. specializing in epilepsy) The Dr. should do an e.e.g , MRI, CT scan, PET Scan along with a complete blood count on you. I found that using nutra sweet and cell phones can cause seizures because it causes more electrical activity in the brain. Migraines, and depression are all a part of epilepsy. One thing that has really helped me is taking vitamin B12 1000mcg. a day. Take note of what the weather is like and if there's a low pressure this can sometimes cause seizures for some people that have epilepsy. You also mentioned that when you take a hot shower you have had a possible seizure, this happened to me also and I found out that the hot water hitting my head triggered seizures so try and take a cooler bath/shower to see if it helps you. I've taken many seizure meds (AED's) over the yrs. and not a single one stopped my seizures. I finally had a DNA blood test done and found out I was drug resistant. You may want to request a DNA blood test so the Dr. can find what seizure meds is the best for you that has the least side effects. I wish you the best of luck and May God Bless You!
