I've had very frequent headaches for the best part of 2 years now, some very strong migraines more often than not on the right side of my head, went to the doctor about it and got put on medication for them a few months back. They minimised them but didn't stop them completely, so I have just been using paracetamol for them. Last week whilst walking I got a numbness in the left side of my tongue which then spread to the left side of my face, then to my left hand, up my left arm then to my left leg. It lasted aout 45 minutes. My vision is sometimes blurry and I get lightheaded very easily and can't see for about 10 seconds when I get lightheaded standing up, it's completely black. I've recently become extremely tired all the time and find it very difficult to wake up (sleep through 6 loud alarms each morning!) I feel myself getting very antisocial these days and have become very quiet and dispondant, and I have started staying in a lot. I'm not sure if it's worth going to the doctor about as I have already been for my headaches and they didn't seem too worried, I was just curious to see if these symptoms seems like cause for concern to anyone?
