I just wanted to get a feel as to whether and of these symptoms are usual or unusual for ME/CFS. I'm looking into POTS currently and wondered whether these symptoms are more indicative of POTS or ME/CFS. I put it here as i'm not sure which sub-forum in the symptoms category to use. Frequent urination (both day and night) Increased thirst (likely responsible for some of the urinary frequency) Hypoglycemia (not sure if it's 'normal' or reactive) Very frequent headaches (often eyebrow type headaches and migraines - often a little better upon lying down) Also wake up with these sometimes. Swollen lymph nodes (both underarms, one side of neck and behind one ear) - seem to swell and then go down Internal tremor type feeling at night-time upon lying down, particually in the legs- sometimes comes with numbness and cramping Muscle aches and joint pain - comes and goes Symptoms often worse when I have any other illness (colds etc) - always get acid reflux when I get a cold now Heat intolerance - often causes bad headaches and blurry eyes. I suffered vertigo once, related to walking in warmer weather. GI, IBS type symptoms - sometimes constipation and sometimes the opposite. Also stomach pain sometimes. Stress intolerance - symptoms seem a lot worse when i'm stressed - particularly GI symptoms I also seem to get bouts of proctalgia fugax after exercise and sometimes testicle pain - both get better after a short while. The thing that confuses me is that I don't seem to get the terrible 'crashes' that I hear so much about, after exercise and exertion I feel a little rubbish but I'm not laid up in bed for days on end. Rather, I just feel a little achy and rubbish overall, I can however still get up and go out sometimes. My onset was likely the most unusual thing, following the vaccination which triggered everything, my major symptom was relentless nausea and vomiting (causing weight loss) and general malaise, often with me feeling lightheaded and headaches. This nausea finally stopped after around 4 months however I am now left with the rest of the symptoms which came on more gradually. If there's one thing i'd like to know is whether swollen lymph nodes can be a symptom of POTS as I personally think many of my symptoms are more consistant to POTS.
