I think drinking does cause backaches and bone problems. I never have had a problem with my back until a couple of years ago I developed lower back pain that bothered me daily. In January I went to detox and a couple of weeks later my back pain was gone, along with a lot of other aches and pains.
My father is 77, a heavy drinker most of his life, he has osteoperosis so bad the doctor says it is uncommon for men to get it that severe. I believe alcohol is a factor.
I read your other post and agree with everyone here that you should seek medical attention for your detox, it can be very dangerous.
