This may seem like a weird question at first. Besides your physical, and cognitive issues do you also have itchiness, crawling sensations, pin prick feelings throughout your body? I sometimes feel this at the lower end of the GI system. Some of these feelings are hard to explain, such as a sand paper or gritty feelings around my eyes, or GI track at times. I also feel clammy, with a low grade fever, and a stronger body odder. Another weird symptom I experience is I break out in what would appear to be tiny pimples on the back of my neck, near the base of the skull. These symptoms along with twitching, stomach pain, and fatigue, for me seem to be more prevalent than the physical pains.
