On my TB test injection site, I was told not to scratch it, but I did press on it hard many times, scrub it with soap with those round soft scrubbers (that comes in dif't colors) when I showered, put lotion and sunscreen on as usual and sprayed perfume on the site. Since they just said not to scratch it if it itches I assumed everything else was ok. Should I tell my Dr. this? Could this alter the test somehow? And would I need to take my test over? If so, how long until I can take the test again? Thanks for any help!
