Last week I had done 3.5 day fast. I broke the fast with organic grapefruit, the yellow kind. I have this funny pain in my back as shown in the areas in the photo below. It is definitely not muscular or bones, but internal. I feel that it may have something to do with kidneys. I do hydrate myslef regularly. Only observation I have is that when I drink black tea, I have the pain more noticeably. I usually do not go to doctors, but since it has lasted one week, I may. If anyone has some information on this or similar experience, I appreciate in advance if you can post here.
Thank you all for being helpful with my fast.
Thank you for the reply and the support it offers. I am going to try another short fast and see how it feels. I am also trying not to eat all the junk and processed foods. I must say it is very hard, especially everyone around me is always offering me junk foods.
My pain comes and goes. Just an hour ago it was just unbearable, but it passed.
