It is barely visible but very palpable although I can see it easily as its my face! It seems worse when I am having a worse that normal time and is usually followed by a worsening of pins and needles, loss of feeling in places and more pain in others, severe mobility problems often taking my mobility away completely and etc etc of other FND symptoms. Does anyone know what it is as it seems directly linked to my FND. also is there anything I can do to help? by the way, I haven't been allergic to anything and as I said it is certainly a symptom as it has been happening for the last 25 years!!
