Pain is different for everyone. But most people will be able to identify different degrees of intensity when they’re suffering from pain or discomfort. In medicine, these degrees are categorised into three main types: mild, moderate and severe.
Over-the-counter medication is available for milder forms of pain, such as headaches and stomach upsets. But for those more severe types of pain, such as after an injury or following surgery, more powerful medication may be required. This type of medicine can only be obtained with a prescription, due to it’s strong analgesic qualities.
