Pain area - Left side flank pain with hot pack

Sudden pain in the left side of the abdomen

There is.

Shall we consider the possible scenarios we can think of in this situation?

There are many cases such as pyelonephritis, shingles, rib fractures, etc., but in my case, I think it was a kind of muscle pain or something similar. Haha, I'm so relieved.

This is acute, so there's no specific answer; just apply a warm compress and make it comfortable.

I think there's nothing else to do but rest.

By engaging in intense exercise or using muscles differently than usual

It is when the muscles in the body become tense or cramp.

It can happen suddenly when you wake up from sleep, especially with your head.

Even when I try to forget (since my head is at waist level...), I sometimes feel painㅠㅠ When I apply heat and wait until time passes, I become okay as if nothing happened, haha. I'm really glad it's not a serious illness.

I think we should avoid slouching or bad posture habits even in everyday life.
