If the pain is noticed in the back after waking up in the morning and it gets better after a while, you need to look at the exact nature of the pain first. If it is a burning pain in the back, it is mostly considered to be caused by gastric reflux esophagitis. Usually at night when sleeping, stomach acid secretion is relatively high and smooth state is more likely to lead to reflux of stomach acid. Therefore, this symptom tends to appear at night and will be reduced in the morning after waking up due to the change of body position. In this case, it is best to go to the gastroenterology department for a gastroscopy to clarify the situation. For this condition caused by H. pylori infection, amoxicillin plus clarithromycin can be used to fight the infection, and acid suppressants such as omeprazole need to be used.
