Microwave thermotherapy is a very clever way to use hot waves to help fix things in your body that aren't working properly. Have you ever put a plate of food in the microwave to heat it up really fast? Well, microwave thermotherapy works in a similar way!
Basically, doctors use a special machine that sends tiny waves of heat into the part of your body that needs help. These waves are called "microwaves" because they are much smaller than other kinds of heat waves, like the ones you feel from the sun.
The microwaves go into your body and heat up the cells in the area that's hurting you. This helps to get rid of pain and swelling, and can even help fix things like tumors or damaged tissue.
But don't worry, the machine that sends the microwaves is very carefully managed by the doctor, so they only heat up the right part of your body, and only for the right amount of time. And it doesn't even hurt! You just lie still while the machine works its magic, and then you can go home feeling much better. Isn't that amazing?
