Blurred vision and numbness in arm/tongue?

My question is why haven't you see a doctor before this? Besides your substance abuse there two diseases that you might have: Trigeminal Neuralgia { It effects the nerves in your face but the pain can be intense} You might have Bells Palsy { It is a viral Infection of the face and causing many of your symptoms. You can temporary paralyzes of the face} Both are treatable. Don't wait any longer.
