Children who underwent this partial removal procedure returned to normal activities in under half the time compared to those who had their entire tonsil removed.
A new study from the University of Eastern Finland found that over 40% of women experience constipation during pregnancy and right after childbirth. Daily exercise, balanced diet, and hydration can help prevent constipation. Lifestyle changes may not be enough to alleviate symptoms, with laxatives needed in some cases.

The study suggests that these patients require a combination of opioids with non-opioid pain relievers to achieve optimal pain management.
Researchers found that SARS-CoV-2's spike protein can suppress pain signaling pathways, leading to reduced pain relief in COVID-19 patients. This discovery may help explain why many people with COVID-19 experience few or no symptoms despite being contagious.
A double-blind, randomized clinical trial found antacid monotherapy to be the most palatable solution and had fewer side effects compared to antacid/lidocaine combinations. Antacid monotherapy was also found to be equally efficacious in relieving epigastric pain as lidocaine/antacid combination therapy.
