A great deal of the messages about threadworms seems to be from parents concerning their children. However, I am 62 and only a couple of months ago discovered that I have this. I have probably had it for a while, but was out and about and changing locations so it wasn't a big problem. Now I am retired it has become a nightmare obsession. My small flat is infected so it is almost impossible to get rid of it. Constant cleaning and washing clothes. When I took ovex twice a day for 3 consecutive days it got better. But then I was re infected. I have a steamer and steam every day. I drink water with 2 tbsp of vinegar twice a day every day. Washed clothes as to be put in sealed holders and kept there for 2 weeks. Eating is difficult. Dishes taken directly from dishwasher. The list goes on and on and it is exhausting.
