I had a pet scan on friday and within minutes of the tracer going in I felt extreme pressure in my top back teeth both sides like something was actually trying to force my teeth out it lasted about 10 mins of the 1 hour waiting time but it was very painful and as i say the feeling of pressure. That evening i experienced quite a few weird feelings in my head like everything sort of stopped =hung=then started again and since friday I have had weird pains and electric shock type feelings in my hands. Just wondering is this something relevant should i mention it to anyone or has this been see in anyone else . 
Thanks
