Why does it still hurt? Is the wound still there?

When you recover from an injury, do you have the experience that you still have some pain (pain scale 1–2 out of 10) after a long period of time and start to feel strange/ sore in parts that were not injured?

To answer this question, you must know more about “pain”.

Pain can be classified as acute and chronic.
Redness, inflammation, sharp pain and swelling is often presented in the acute phase. When the pain persist for more than 3 months, it turns into chronic pain.

TMJ (temporal mandibular joint) dysfunction, degeneration joint diseases, pelvic pain, visceral pain and myofascial pain, are common forms of chromic pain.

Chronic pain is common among us, the proportion is as high as 20~25%. There are many who suffer from “pain” all their lives trying to find a solution for recovery. According to studies, people with chronic pain are more likely to develop depression and anxiety; acute pain is more likely to evolve into chronic pain in those with depression family history.

Thus, psychotherapy is as important as taking drugs and injection.
