I've been a CFS sufferer since 1983 and I've been in a fairly severe flare for about 2 years. After many years of denial, I accepted my diagnosis of CFS but when new symptoms crop up, I am never sure what to do. For the last few months, I've had moderate to severe muscle pain in my upper back that was first on the right side and is now on the left. Although I'm pretty sure it's CFS because I've experienced similar muscle pain over the years, I can't help but worry that it's something else and my already taxed adrenals can't take much more stress. How does everyone deal with the mental anguish about whether or not to seek additional medical treatment? I can't even remember the number of times I've had the phone in my hands wondering if I needed to call 911 but, of course, didn't. This is no way to live.
