My whole body aches, my back aches and my legs ache. What happened?

1 As you described, if you have some pain all over your body, including some pain in your waist and some pain in your legs.

This situation may be the cause of some fatigue, for example, I may have to do something in the near future and didn't pay much attention to rest. It's easy to feel a little sore all over. There is a similar situation, that is, if you may have some regular physical exercise in the near future, you will be prone to pain all over. Therefore, if it is because of these circumstances, we should pay more attention to rest in the near future, and now we can do some appropriate exercise to relieve it slowly.

2, like general pain, low back pain, may be the reason for your body to catch cold.

For example, I used to have some pains in my back or legs, or some injuries. It may be cold now, so I don't pay much attention to keeping warm. You will easily feel a little cold. Even when I slept at night, I didn't pay much attention. In these cases, you can also put some hot towels on your painful parts for hot compress, and then rub them with your hands, which can help relieve the pain.

3, usually consider whether it is because of the lumbar spine, it will be prone to similar pain.

Usually, if you often bend over for a long time to do things, or often climb mountains, it is easy to have low back pain, including leg pain. These are also because my waist and legs feel a little stressed. If this is the case, try to sit down and have a rest and don't do too much exercise for the time being. But these pains are gradually relieved, and then corresponding exercise is carried out.
