Glad info was useful. I had quite a few low thyroid symptoms - constipation, receding hairline, flaky nails, mental fatigue, tearful. I attributed it all to menopause, until I started bruising quite dramatically at slightest knock. No weight gain though which is a classic symptom. Ive just looked up the connection and it is apparently that 1 in 4 LS suffererers also have an auto immune condition such a thyroid deficiency.
Re LS- I'd forgotten about Yes OB - tried it thought it was good, but a faff having to stand it in hot water for a few minutes before I could get any out of the bottle. Just had another look at their website and see that it's been changed, so maybe worth another try.
Hope your LS starts to clear up before too long. I found once I had it under control, it has been stable and I now self-manage. I have a 10 x magnifying mirror I use to check myself regularly for changes that could be any early signs of cancer, which I guess is what you are worrying about. I was a bit freaked by that risk too at start, but was assured by consultant that its quite rare. Had forgotten about it until I read your post.
