I am poisoned. I think it was triggered by contact with Ivy. It causes a reaction that takes a few days to reach full rage. I have furious itching on my hands, especially on the webbing between fingers. On advice from the NHS, tried an anti-histamine. The cure was worse than the illness. Saturday I spent the day with the feeling you get in the days after a cold- detached, listless and fuzzy headed. Hydro-cortisone seemed to reduce the irritation, but it still took nearly a week.
