I recently had bloods before starting the cycle, all good. I'm about to start week 4 today. I tremble & my memory is shot, I have to word substitute to avoid embarressment also I have had pain in my legs for about 6 weeks now, but once my muscles warm up I'm ok, as soon I sit, my muscles tighten up and the pain comes back. I have begun to stammer as well. Every time I eat, I belch badly. It's like I'm going into spasm. I had my electrolytes checked, all fine. My G.P has referd me to a neurologist. I opened the referal letter. It had my medication list & recent complaints & there was this? -MS??- Two letters with question marks. I am worried.
