First, how to pronounce this word – dysesthesia – (dis-uhs-thee-zhuh). Now that that's settled, what exactly is it? According to the dictionary it's an impairment of the senses – especially touch. Even a very light touch can cause pain.
It's derived from two Greek words – “dys” – which means “not normal”. “Aesthesias” means sensation. Together they mean abnormal sensation. It can be an unpleasant touch that is sometimes described as painful.
These sensations are caused by lesions in either the central nervous system in the case of MS or the peripheral nervous system. These sensations can be either spontaneous or evoked. What do you feel when you have these sensations? You can feel the following:
