I am 90 percent recovered thanks to all of you. I still have histamine issues and react to mold still.

I had an issue with my downstairs bathroom recently. We found mold in the shower drain! It was causing symptoms neurologically during shower time. It got worse as I ran the water and steam would fill the room. After cleaning the P-traps, it was much better.

I just recently started using the upper bathroom due to construction going on downstairs. Well the whole week I would leave the shower with hives, anxiety, rapid heart rate, and burning eyes. Come to find out, mold in the drain!

So long story short, clean your P-traps! The sink and showers. We used vinegar and baking soda with a long drain scrubber. Wear a mask! I periodically pour hydrogen periodically down the drains and let it soak during work.
