受傷後的身體會發出一些的信號，引起你的注意，應該將這些普通的提示作為身體發出的警報。有些運動創傷會即刻顯現出來，而另一些則會不知不覺地顯露出來並趨於惡化。如果對這兩種類型的創傷不加以注意，就可能發展成為慢性疾病的受害者。

不要忽視那些運動傷害的警訊

關節痛
關節痛，尤其是膝蓋、腳踝、手肘和手腕部位的疼痛，是不可小視的。因為這些關節不是由肌肉包裹的，所以這些疼痛源於肌肉的可能性極小。如果關節痛超過48小時，就需要醫生的診斷。

敏感的特定點
如果能用手指按在疼痛的部位上，明確指出它位於骨頭、肌肉或關節的某一點，那麼你可能受到了嚴重的創傷。如果身體另一邊的相同區域感覺不到相似的疼痛，你可能需要去看一下醫生。

腫脹
幾乎所有的創傷都會引起腫脹。腫脹通常是顯而易見的，而少數情況下你會有腫脹的感覺但卻很難觀察到腫脹的現象。腫脹的同時一般還會有疼痛、發紅、發熱的現象。關節部位的腫脹通常會引起疼痛、發硬；而將腫脹部位推到別的位置時，肌腱之間相互摩擦可能會發出咔嗒聲。

活動範圍受到約束
如果腫脹不太明顯，通常會發生關節活動範圍受到約束的現象。如果關節存在嚴重的腫脹，就會無法活動——肢體在每個方向上的活動範圍都十分有限。然後可將發生病痛的部位與身體另一邊相對的位置進行對比，確認其間是否存在較大的區別，如果有，可能就需要對此加以重視了。

相對較弱
將受傷的部位與身體另一邊相對的部位相互比較強弱，一般來說是很難的，但這種方法有助於評定創傷。方法之一是使用左右兩邊分別提起相同重量的物體，觀察結果；或者嘗試雙腳分別做單腳獨立，如果發現它們的支撐能力有所差別，就表示身體在向你發出另一個信號：這是需要引起重視的創傷。

無知覺或感到刺痛
不要忽視無知覺或刺痛的感覺。這些通常與神經壓迫有關，這些警報可能意味著身體遭受了嚴重的創傷，通常極易通過醫生診斷發現。

There are some common tip-offs you should recognize as warning signs that you have an injury that needs your attention. While some sports injuries are immediately evident, others can creep up slowly and progressively get worse. If you don't pay attention to both types of injuries, chronic problems can develop.

Don't Ignore These Sports Injury Warning Signs

* Joint Pain
Joint pain, particularly in the joints of the knee, ankle, elbow and wrist, should never be ignored. Because these joints are not covered by muscle, pain here is rarely of muscular origin. Joint pain that lasts more than 48 hours requires a physician's diagnosis.

* Tenderness at a Specific Point
If you can elicit pain at a specific point in a bone, muscle or joint, by pressing your finger into it, you may have a significant injury. If the same spot on the other side of the body does not produce the same pain, you should probably see a physician.

* Swelling
Nearly all sports injuries cause swelling. Swelling is usually quite obvious and can be seen, but occasionally you may just feel as though something is swollen even though it look normal. Swelling usual goes hand-in-hand with pain, redness and heat. Swelling within a joint often causes pain, stiffness, and may produce a clicking sound as the tendons snap over one another after having been pushed into a new position from the swelling.

* Reduced Range of Motion
If swelling isn't obvious, you can usually find it by checking for a reduced range of motion in a joint. If there is significant swelling within a joint, you will lose range of motion -- the limb will only go so far in each direction. Again, compare one side of the body with the other to identify major differences; if there are any, you likely have an injury that needs attention.

* Comparative Weakness
Comparing one side to the other for weakness is often hard to do, but can be helpful when assessing an injury. One way to tell is to lift the same weight with the right and left side and look at the result. Or try to place body weight on one leg and then the other. A difference in your ability to support your weight is another tip-off to an injury that requires attention.

* Numbness and Tingling
Never ignore numbness or tingling. Such sensations are often related to nerve compression, and these warning signs may indicate serious injury that should always be seen by a physician.
