Hey, I have not been officially diagnosed with CFS yet. My GP has referred me to a CFS specialist and I will be seeing her shortly. Reading though these forums, I'm 95% sure I have CFS. My symptoms include PEM, brain fog, persistent fatigue all the time (not sleepiness), stomach problems, stuffy nose and phlegm in the morning. I've had these symptoms for around two years and have done blood, stool, urine, ultrasound, and x-ray tests. All the tests are normal. However, I'm not 100% I have it, because I have no pain whatsoever, no temperature regulating problems, no heart or neurological problems and no sleep problems (Sleep is not refreshing ,but nothing other than that) I went to see an ENT and he told me I have slightly large tonsils and he told me to take a sleep test, to check for OSA. I think there might be no point in doing this test, as from what I read my symptoms cannot be explained by OSA. I mean, how can OSA explain PEM with flu-like symptoms? Should I just skip the sleep test and just wait to see the CFS specialist? I'm getting tired of doing all these tests that are seemingly pointless. I'm also going to see an endocrinologist, although my TSH is normal according to blood tests, and I don't have swollen lymph nodes.
