I have been looking into OI as i get alot of brain fog/fatigue if standing or sitting for along time and find if i lie down for 10min i feel better, i have experimented with sudafed which has helped.The last few days i havent had any sudafed etc but have had hypertensive, tachycardic episodes, i didnt feel anxious and have had these feeling in the past whre i get the sweats and head has a pressure in it etc but they go after an hour(never worried about taking BP then) or so, but the last 2 days it hasnt stopped. One time my bp was 160/120 P-110, after this i started to become concerned as it didnt pass and kept going. My cfs doc is on holidays at the moment so couldnt see him, so saw our old family doc who my wife still sees and i havent seen for years. I stopped seeing him as he didnt have much to offer for cfs, so today when i saw him he dodged the whole autonomic dysfunction with cfs stuff in a nice way, probably because it was over his head and said it was anxiety related etc. I didnt mind this i was just after something to manage the symptoms, beta blocker would have been nice but think that was asking too much but did give me some valium, if its anxiety or autonomic dysfunction i suppose treatments can be similar. I can see how some people can have problems getting help from a doctor when they arent upto date on cfs matters. Whats a concern for me is that now i have my viral stuff in check, it seems this autonomic crap is playing up. Im going to keep an eye on my BP as i havent checked it and seen it low, maybe its always borderline high when i feel strange in the past, maybe its poor cerebral circulation. I dont feel like its a panic attack, maybe it is, i just dont know. Im not sure what to do now, do i walk around with some valium in my pocket all the time?? I know my adrenal hormones are low, maybe its a sign there starting to wake up. I felt abit lost without my cfs doc, i was thinking of going to the hospital but know its not great there either. Appreciate any tips for this type of autonomic dysfunction. cheers!!!
