Scary electric shock?

 I had that same fear back when I was in my 20s.  Plus all the symptoms you could possibly think of… muscle twitching, tingling etc. I had and still sometimes have all those symptoms of anxiety  also. I thought I had Terrible diseases and a zillion other things. When I was in my 20s I thought for sure I was going to get a MS because my aunt had it. That thinking was based solely on non-reality. I never developed a MS but I tortured myself by thinking so negatively! All my test came out perfectly.   It sounds like you were doing the same thing with your fear of cancer. As long as you get checked out by your doctor and the test come out good, you really need to put that out of your mind. If you can't do it on your own and sometimes it's hard to, I highly suggest talking to a counselor who can really help. As we all know anxiety can produce so many and such scary symptoms.

 it doesn't pay to read too much online, all we do is scare ourselves more. There is a MUCH HIGHER likelihood that your  symptoms are caused by stress and anxiety then some terrifying disease.  

 we can't let anxiety run our lives and our minds. We are better than that and we deserve to feel healthy and enjoy life. We need to be relentless in the pursuit of our health including healthy minds.  I once heard the saying "don't believe everything you think "which is so very true.   Our minds  are  so powerful and  go to the negative if we let it.  I have battled anxiety since my 20s and I am now in my 50s. I'm at the point where  I know the anxiety symptoms so well and pretty much ignore them telling myself it will pass. You need to stay active so you're mind isn't focused on the negative.  I have found meditative audios online that deal with stress and anxiety to be very helpful, also regular exercise, eating healthy and socializing. Doingsomething for someone else can make you feel great and it takes the focus off of yourself and your worries.

The worst thing we can do is isolate ourselves which causes us to think more and more negatively. As long as  we follow up with our doctors and if the tests come out normal we really have to work hard at thinking more positively. You can find great books at the bookstore on the power of the mind and stress, depression anxiety. 

ALL THE "WHAT IFS" ARE VERY HARMFUL TO OUR MENTAL HEALTH". What if's are NOT based in reality. It is our mind going to the negative. 

Please don't do this to yourself.! I wasted 30 years with the "what if "thinking and nothing bad ever happened! I think if you had brain cancer you would definitely know it and your doctor would have found it. There is a 99.9% chance an MRI would be completely normal. Another reason to get help such as a counselor is that chronic negative thinking Can actually make negative changes in the brain. Rest assured, I don't mean cancer.     I highly suggest seeing a counselor who can provide tools to help you overcome this. It really helps and has been my lifeline! I go even when I start to feel better.

Take the focus off of yourself by possibly doing something for someone else.

KEEP THIS IN MIND.....FEAR STANDS FOR.   False Evidence Appearing Real.    Fear is based out of non-reality

Stay Active, exercises dramatically reduces my anxiety! Socialize, eat healthy, look for free meditative audios online related to negative thinking.  They really help! 

 Also I have had every one of the symptoms you listed and they were all anxiety related!  Yes also the electric shock I've had it in my neck? Please stay off those Internet sites they only scare people to death. And just to let you know, I had those symptoms 35 years ago and I'm still here, healthy and happy.  You can do this! Be a fighter. 

Hi, ImAnon I just wanted to respond as I have everything you have listed.

Little pressure type headaches on top of my head as well as the head pressure, vertigo (which can be either constant or ease off,) ears ring a bit, as well as the dreaded brain zaps.

This has been happening to me for twelve months now but I have been battling g with severe anxiety side I was little. You aren't on your own.

Like you I have had many GP visits. I have visited the same one multiple times for continuity, as well as getting other GP's opinions on it and the resounding answer has been anxiety.

I found that therapy has helped me quite a bit and the symptoms are now not there all the time. If I am particularly 'bad' they stay until I ease.

It's very hard to sometimes accept these things as anxiety, especially when the feelings and sensations are so real. In a way they are perfectly real, but they are not caused by anything sinister.

You did the right thing in being checked. It always pays to check with a GP first when it comes to health concerns, but if they are all telling you the same thing then I think you need to look at your other options... Which is most likely counselling.

I understand your frustration with needing an MRI to be that definitive proof that you are ok... But I warn you that may not be easy if you are in the UK and are unable to pay privately. if they do not think you need the test then they are unlikely to send you for one.

Perhaps try and source therapy and you can detail your concerns with them.
