Welcome to HCM
We understand your concerns
I went through your problem description. I suggest not to worry. You copuld have mentioned your age.
You are unable to explain the feeling and you never had epilepsy
and you suspect it might lead to epilepsy. That may be cause of your unexplained feelings. Please don't worry about diseases which you do not have. Don't imagine that you are having those diseases which actually you don't have. that is dangerous and may lead to mental troubles.
Change the position of your bathing and use warm water for taking bath. That should cure your problem.
Hope this clears your doubts. Available for further clarifications
