What is the difference between the nitrogen used by my doctor and the nitrogen in Dr. Scholl's Freeze Away product? Why is the latter prohibited during pregnancy?

The main difference between the nitrogen used by a doctor and the nitrogen in over-the-counter products like Freeze Away is the temperature at which they can reach. The liquid nitrogen used by a doctor can reach -50°C in just 30 seconds, whereas the products available at stores do not get as cold as quickly. It is important to note that over-the-counter products have been associated with cases of frostbite due to mishandling at home. It is always advisable to consult a healthcare professional before using any treatment during pregnancy, as many over-the-counter medications may not have been studied specifically in pregnant women. It is generally recommended to opt for treatments like liquid nitrogen or salicylic acid-based products that are known to be safer during pregnancy.
