I dont know what to do, I made some calf liver last week and after that I started to feel pain in my neck, I could not put 2 an 2 together, I did not know what has been the source of problems. Everything is making the neck problem worse now ,chocolate, cheese, milk, riccota after that now. Then I had liver again this week, 2 days ago and the pain got unberable that day, cold it be all that vitamin A. By today the pain got little better but still, did anybode else have this problems??
