No known medical conditions and I'm just taking the contraceptive pill.
OK XXXXX. With the attack yesterday was there diarrhea like the last time?
No. This time it was much milder. It was just the itchy/burning hand (just one this time), racing heart, feeling faint and sweating. The itchy/burning hand was constant, but the other symptoms came on in bursts. No abdominal cramps or diarrhoea like last time.
OK XXXXX. That one attack with the diarrhea and flushing sounds very much like what's called carcinoid syndrome which is a rare thing involving a gastrointestinal tumor that secretes serotonin. This could be something simpler like irritable bowel syndrome but that one attack was classic for carcinoid syndrome. You need to see a doctor as soon as you can for a workup for this
Thanks for getting back to me. Would carcinoid syndrome explain the burning/itchy hands because that's how it started and it appeared to be quite a strange symptom to me?
Yes it could XXXXX. It goes along with the flushing that people get and it's a little like a histamine release reaction from an allergic reaction
Also, the flushing associated with carcinoid syndrome appears to be dry, whereas I was sweating profusely.
Yes. Most of the symptoms of hyperthyroidism I only experience occasionally. The only constant one seems to be the sweating, as I notice I seem to sweat a lot more than other people generally. Is there anything else that you think it might be, or is that it? Obviously, I'm aware I need to see a doctor; it's just that it looks like it might take a few weeks.
Well, there's always the old default diagnosis of anxiety attacks but before you can chalk it up to that you need to rule out other possibilities. Let me know how it goes and please remember to rate my service to you XXXXX
Thanks for your help.
