Hi Joanna, I am hoping that you are experiencing an acute phase. Many conditions have these. Some of the symptoms fit ,others don't.(always the case). I had a diagnosis that ranged from one Dr to the next. Periferal Neuropathy, Amyotrophy. I had muscle wasting, lost 60 lbs, knee pain butt pain,lumbar pain, had to start using a walker. But things are turning around!! It is not so bad now. If you use the search engine here, maybe you can read about the mottling of the skin. I remember others. If you are caring for a two-year old there is no need to talk about excercise but there is a universe out there of sufferers ready to help w/ niutrition, vitamins,pain, sleep, etc. Good Luck, Ken in Texas.
