I feel really weird and keep getting electric shocks

[Ch0pp3r]

Hi folks

Posting here as hoping somebody can help me.

For the past 2 months or so I have been having what I am calling attacks. Up to 3-5 times a day. I'll describe an attack. Basically I'll be doing things as normal and then I'll start to feel really weird which is hard to describe. Best I can do is that something is wrong and that's things feel surreal. Then I'll start to get pins and needles in my face, usually just one side, jaw and temples. Pins and needles in my hands and legs. Numbness starts as well and all along it feels like something is building up. Like an energy is building. This all can last for quite awhile and then it is usually ended with an electric shock. Most of the time it's to my head and will make my body fully jerk which is painless. Or i will get the sensation that I am on a roller coaster doing a 100mph plunge with my stomach trying to go into my chest. Usually when the final shock happens, extreme tiredness kicks in and I need to sleep or I'll sometimes get the nothing is real and extreme fear kicks in like the ultimate fear. I'm going to die. Everybody is going to die. Run away and hide if you can kind of fear.  If I can sleep, it's usually for a couple of hours but before I sleep I will get more electric shocks that make my body jerk.
Now NHS being what it is I am finally seeing a neurologist next week as this has caused me to end up in casualty 3 times in the past month and now the neurologist appointment is a rapid access appointment. My GP had referred me to a neurologist as she said they are the ones that deal with "seizure type / MS type symptoms" and the casualty nurse more or less said the same. I tried to stay off google but as this, whatever it is, is currently ruining my quality of life, I have been googling. It does sound like I could have MS or I'm having temporal lobe partial seizures.
So my questions are really 1. What am I looking at? 2. Does it sound like I am having partial seizures? 3. What will happen on Thursday? Dr asks questions and then refers me for more testing eg MRI and brain scan so I will be stuck like this for at least another 12 weeks? 4. Is there anything that I can do to help myself in the mean time? Because this is really starting to get to me.

Any help or advice greatly appreciated

Thanks

Chris
