Whenever this hooking starts, I will receive a very sharp pain that may last for hours, and in the midst of this pain, I will also have stomach disorder. During this period, it will seem as if I am going to vomit, but will not, and I will feel so uncomfortable throughout the period it will last. Initially, I thought it was worm, and had to get some worm tablets, but for the past one month now, it has persisted. I was later informed that it was cold, and I have been using some balm to massage my back, but no improvement yet. Please, what exactly is it and what do I do about it?
