Hi...I Don't Know What Has Been Going On With Me.

Hi...I don't know what has been going on with me. I'm experiencing episodes that last 2-3 minutes, I become extremely weak, disoriented, I feel as if I'm going to pass out, I feel as if electricity is going thru my nerves. Once the episode passes I am exhausted and feel as if I could sleep a couple hours. My husband has suggested perhaps it's panic attacks. Your thoughts?
