The Left side of my mouth is numb and doesn't move properly plus now the left side of my tongue is starting to feel funny. I'm 24 and I am a welder. This only happened 2 days ago but I'm starting to worry because I can't even spit out my toothpaste properly. I have had lots of muscle issues in my neck and back for the last 6 years. The neck pain gives me terrible headaches.
What could be causing this numbness now?
