My daughter after 3 weeks of non smoking, began to do the same thing that you are talking about. Swelling under her right rib cage to the point of so much discomfort. At the same time she quit smoking she began eating more and more raw veggies and fruit which she had never been able to do much of. Our chiropractor told her that the liver was taking on that detox load. I am glad to read about MH's Lethicin help. I will order some. Right now I am making her smoothies with raspberries, blackberries, Milk thistle, and dandelion root. I am glad to have read your post. Thank you.
