不(bu)少的(de)疼(teng)(teng)痛患者(zhe)(zhe)，經過長時間檢查(cha)，也查(cha)不(bu)出引起疼(teng)(teng)痛的(de)原(yuan)因(yin)(yin)，不(bu)知道該看哪(na)個科，這(zhe)類患者(zhe)(zhe)經過疼(teng)(teng)痛科醫(yi)生(sheng)的(de)檢查(cha)，包括(kuo)診斷性(xing)治療(liao)，絕大部分是可以(yi)找到原(yuan)因(yin)(yin)，采取對因(yin)(yin)治療(liao)的(de)。比如(ru)有的(de)患者(zhe)(zhe)腿疼(teng)(teng)，就(jiu)掛(gua)骨(gu)科，骨(gu)科醫(yi)生(sheng)建議看神(shen)經內科，神(shen)經內科又建議去理療(liao)科看病，也沒找出的(de)是什么毛(mao)病，這(zhe)種情況就(jiu)要考慮疼(teng)(teng)痛科，但很多患者(zhe)(zhe)根本不(bu)知道有這(zhe)個科室，查(cha)不(bu)出病因(yin)(yin)，就(jiu)只能忍痛。

如帶(dai)狀皰疹(zhen)后疼痛(tong)(tong)(tong)(tong)、幻肢(zhi)痛(tong)(tong)(tong)(tong)、三叉神經痛(tong)(tong)(tong)(tong)等(deng)。像帶(dai)狀皰疹(zhen)后遺神經痛(tong)(tong)(tong)(tong)這(zhe)類(lei)疾病，盡管皮膚好(hao)了，但是頑(wan)固性(xing)疼痛(tong)(tong)(tong)(tong)一直持續下去，這(zhe)種疼痛(tong)(tong)(tong)(tong)一定要到(dao)疼痛(tong)(tong)(tong)(tong)科去治(zhi)療(liao)(liao)，且越(yue)早治(zhi)療(liao)(liao)的(de)效果(guo)越(yue)好(hao)，但很多(duo)人并不能(neng)及時排查出病因，得到(dao)針對性(xing)的(de)治(zhi)療(liao)(liao)，給患者增(zeng)添了不少痛(tong)(tong)(tong)(tong)苦。

頸、肩、腰(yao)、腿(tui)這(zhe)四(si)個部位，經(jing)常(chang)會在運動過程(cheng)中(zhong)發生(sheng)磨損。而磨損早期沒有(you)明顯的(de)(de)骨骼和肌肉改變，僅(jin)表(biao)現為疼痛(tong)(tong)(tong)(tong)(tong)。這(zhe)些(xie)疼痛(tong)(tong)(tong)(tong)(tong)如(ru)果在其他科室治療(liao)，可能會簡單地開一些(xie)止疼片，要你加強鍛煉等等，但這(zhe)一大(da)類疾(ji)病(bing)(bing)應該到疼痛(tong)(tong)(tong)(tong)(tong)科治療(liao)。如(ru)果關節(jie)(jie)非常(chang)疼，去了(le)很多醫院都(dou)說問題不(bu)大(da)，止痛(tong)(tong)(tong)(tong)(tong)藥吃了(le)就好(hao)，不(bu)吃就疼，建議到疼痛(tong)(tong)(tong)(tong)(tong)科進行除服藥以(yi)外的(de)(de)綜合治療(liao)。事實上，把疼痛(tong)(tong)(tong)(tong)(tong)的(de)(de)問題完善地解決了(le)，骨關節(jie)(jie)疼痛(tong)(tong)(tong)(tong)(tong)部位的(de)(de)血液循環就會好(hao)起來，對(dui)關節(jie)(jie)本身也(ye)(ye)有(you)好(hao)處。另有(you)一些(xie)脊柱四(si)肢(zhi)的(de)(de)疼痛(tong)(tong)(tong)(tong)(tong)，如(ru)椎間(jian)盤突出(chu)、頸椎病(bing)(bing)等，患者既不(bu)愿意接受(shou)手(shou)術(shu)或沒有(you)手(shou)術(shu)適應癥，單純(chun)服藥又療(liao)效(xiao)不(bu)好(hao)，也(ye)(ye)應該到疼痛(tong)(tong)(tong)(tong)(tong)科治療(liao)。

如類風濕性(xing)關(guan)節炎、強直(zhi)性(xing)脊柱炎、痛風等。

如中樞(shu)性痛、反射性交感神經(jing)(jing)萎縮癥、三叉神經(jing)(jing)痛、舌咽(yan)神經(jing)(jing)痛等(deng)。

當病人(ren)(ren)不(bu)幸患上(shang)癌(ai)癥，我們(men)在(zai)治(zhi)療(liao)癌(ai)癥的(de)(de)(de)過(guo)程(cheng)中，決不(bu)能(neng)放棄(qi)或輕視疼痛(tong)(tong)治(zhi)療(liao)。一般來(lai)說，癌(ai)癥本(ben)身對人(ren)(ren)體的(de)(de)(de)消耗是個慢性(xing)過(guo)程(cheng)，但一旦出(chu)現嚴重的(de)(de)(de)癌(ai)性(xing)疼痛(tong)(tong)，這種惡(e)性(xing)疼痛(tong)(tong)刺激對人(ren)(ren)體的(de)(de)(de)損害比癌(ai)癥本(ben)身還嚴重，可(ke)(ke)以(yi)迅(xun)速把人(ren)(ren)體摧(cui)跨。很多(duo)醫學研究表明(ming)完善治(zhi)療(liao)癌(ai)痛(tong)(tong)，不(bu)僅可(ke)(ke)以(yi)提高患者生(sheng)活質量，還可(ke)(ke)以(yi)延長患者生(sheng)命(ming)。
