As it is another week and different symptoms. I'm getting a strong throbbing in my head when ever I get up from lying down or bend over, blurred vision, pressure in my skull and eyes and confusion. And also a little off balanced and crazy headaches. Certain parts of my body twitches strongly for a really long time and I usually feel my feet pulsating strongly. I've had a ECG done and everything is OK. So is my bloodcount. I've read that cancer/ tumours can cause most of the above... Any suggestions???
