上期我跟大家談過「拉腰」治坐骨神經痛這個話題，後來有人問我物理治療中是否有一項叫「拉頸」的方法，用作治療頸椎神經線受壓呢？不錯，其實頸椎神經跟坐骨神經一樣，都會因受壓而出現肢體感覺上的錯亂，而他所說的「拉頸」，便是其中一種頗為常用的治療方式。
近日有讀者來信，說她患了腰痛多年，近日痛楚更延至右腿外側，有時甚至擴散至小腿部分，間中還會出現麻痺感。

昨天跟一位教車師傅聊天，發現原來他跟許多職業司機一樣，由於長時間坐在又軟又低的司機位上而患上「椎間盤性」的腰痛。近日更因此而引起坐骨神經痛，使他一旦久坐後便會出現腿部痺痛，極為不適。

It is likely that junk food is as addictive as drug, and it may as well applicable to human.
Glycosaminoglycans(GAGs) are linear polysaccharides made up of negatively charged disaccharide repeating units. Based on the structures of the repeating unit, GAGs can be classified into hyaluronan, the chondroitins, the keratins and the heparans. In tissues, the GAGs are covalently linked to the core proteins of proteoglycans. Metabolic turnover results in internal cleavage of core proteins or component GAG chains and thus ...
