Persistent swelling is a sensation that occurs due to some kind of damage or irritation of the organism, and the pain is felt differently depending on the location of the lesion. For example, if the headache is persistent and accompanied by symptoms of vomiting, it means that the intracranial pressure is increased at this time, and the patient often develops a brain hernia. If there is persistent abdominal pain accompanied by a burning sensation in the stomach or bloating, a peptic ulcer is most likely to be considered. Although pain is a very common phenomenon in daily life, it still should not be ignored. When persistent pain occurs, it is necessary to consult a doctor in time, through a series of detailed examination to rule out the cause of the disease, so as to do targeted treatment. At the same time, if the pain is more severe, you can take oral anti-inflammatory, pain relieving tablets, such as oral ibuprofen for relief.
