There seem to be so many illnesses with similar symptoms that it really makes it hard to diagnose anything for sure.Very interesting about the CFS. I will have to check it out online.I know Lupus has some similar symptoms, but much worse outcome.I am so amazed at all the "new" illnesses of our times. How much is stress. How much is caused by the way our society lives with all the pesticides, hormones, etc. that continue to build up. How much has always been around but they just never had a name for it. I look back now and I am certain my mom had fibromyalgia but she was never officially diagnosed.
