However, postoperative pain is managed well in hospitals. Postoperative pain can be managed non-pharmacologically or pharmacologically. Non-pharmacological methods include hypnosis, hot and cold compressions, massage, acupuncture, and nerve stimulation. Drugs that can be used are paracetamol, opioids such as morphine and codeine, nonsteroidal anti-inflammatory drugs (NSAID) such as diclofenac and ibuprofen and ketamine.
