But I think I finally figured out what has been causing my rash, nearly 2 weeks later. My new bedsheets.
I bought the sheets on our anniversary trip, tossed them into the washer and put them on the bed Sunday night. Monday afternoon I'm noticing the dots. A week later Sunday I'm washing the sheets all over again, just in case. Along with all the other bedding. The rash still persists.
Last night I woke up after 2 hours of sleep and could not stop itching. Oh. So. Painful. So more than an hour later I get up and take some medicine and then I went back to bed. The pain persists. Finally wildly wondering... what if I took the sheet off? So I popped off my end of the sheets and pushed it all towards my husband (yeah, I'm a loving wife like that, I didn't want to wake him up at 5am) and in 10 minutes I was feeling soooooo much better. I doubt the medicine could have kicked in that fast.
Geesh, you'd think I would have figured it out faster! The picture is of my right side - a side I like to sleep a lot on. In fact that rash is dominantly on parts of the body that touch the sheets the most. My front and sides are badly rashed, my back not so much.
The sheet is a fitted queen size bedsheet from IKEA, brand new, 100% cotton. Washed with the laundry detergent that I've been using for the last 3 years and vinegar in the rinse cycle. I wouldn't recommend buying it. :P
Hopefully it'll abate soon! :)
