|Have you identified PI in the yard? If so...
Remember, if you keep getting new bumps, then you are coming in contact with urushiol somewhere, it cant spread by scratching.
The only way to contract an allergic reaction to PI is by coming in direct contact with urushiol. More than likely, just like any other oil, it washed down the drain the first time you bathed. If youre unsure a good degreaser like Mean Green should do the trick. I'd wipe down all handles, nobs, etc with degreaser then lysol. Those are more likely the culprit. Depending how many times you keep breaking out, washing all clothes, shoes that may have even a spot of urushiol; and vacuuming or shampooing carpets cant hurt. urushiol can survive for many many many years. I've heard 5yrs to 500!!!! Remember, if you keep getting new bumps, then you are coming in contact with urushiol somewhere, it cant spread by scratching.
