For example, pain in the upper left abdomen is mostly due to problems in the gastrointestinal tract. If the pain is prolonged, a gastroscopy should be done in the gastroenterology department to determine whether it is gastritis or other problems. If it is gastritis, you can take drugs such as Daxil and omeprazole. If the pain is in the left lower abdomen, sometimes it is a tension or spasmodic pain, it is necessary to clarify the cause and do ultrasound of liver, gallbladder, pancreas, spleen and kidney, then only antispasmodic drugs such as atropine, 654-2, etc. are used. If the pain is in the lower right abdomen, this is the time to exclude acute acute abdomen, appendicitis, and for women, consider whether there are ovarian problems, ectopic pregnancy problems, etc. After finding these causes, you can take non-steroidal painkillers, such as ibuprofen and fenpropathrin, to solve the pain problem.
