While pain medications can provide significant relief, they also come with potential side effects. Non-opioid analgesics can cause gastrointestinal issues, such as stomach ulcers and kidney problems. Opioids may lead to constipation, nausea, drowsiness, and, in some cases, dependency or addiction. Adjuvant medications also have their own set of side effects, such as dizziness, dry mouth, and mood changes.
